TPS54560BDDAR

LM2596S-12/NOPB is a Texas Instruments LM2596 SIMPLE SWITCHER fixed 12 V step-down (buck) regulator — 3 A, 4.5 to 40 V input, 150 kHz fixed-frequency internal oscillator, in the 5-lead TO-263 surface-mount package (S), tube packing, NOPB lead-free, operating -40 to +125 °C. The fixed 12 V version is the selection point: the classic 24 V industrial bus down to a 12 V rail with no feedback divider, so fewer external parts and no resistor-tolerance error — the datasheet circuit needs only four external components. Selection advice: choose the fixed 12 V code when the rail is known (5 V and 3.3 V codes exist in the same family) and the adjustable LM2596S-ADJ only when the voltage must be trimmable. The 150 kHz frequency keeps the design simple and cheap but demands a larger inductor than modern megahertz switchers, and as a non-synchronous part it cannot match modern synchronous bucks on light-load efficiency — check that trade before committing. Thermal shutdown, current limiting and TTL shutdown are built in. The S (TO-263) is the SMD package; for through-hole heatsinking look at the T (TO-220) codes. Evidence: TI/National LM2596 datasheet and distributor listings confirm 12 V fixed, 3 A, 4.5-40 V, 150 kHz and TO-263. Match the full LM2596S-12/NOPB code for voltage, package and lead-free packing.

LM2596S-3.3/NOPB is a Texas Instruments LM2596 SIMPLE SWITCHER fixed 3.3 V step-down (buck) regulator — 3 A, 4.5 to 40 V input, 150 kHz fixed-frequency internal oscillator, in the 5-lead TO-263 surface-mount package (S), tube packing, NOPB lead-free, operating -40 to +125 °C. The fixed 3.3 V version is the selection point: no feedback divider, so fewer external parts and no resistor-tolerance error on the output — the datasheet circuit needs only four external components. Selection advice: choose the fixed-voltage code when the rail is known (3.3 V here; 5 V and 12 V codes exist) and the adjustable LM2596S-ADJ only when the voltage must be trimmable. The 150 kHz switching frequency means a larger inductor than modern megahertz switchers, but also a simpler, cheaper, well-understood design — the trade to check is light-load efficiency, since this non-synchronous part cannot match modern synchronous bucks there. Thermal shutdown, current limiting and TTL shutdown are built in. The S (TO-263) is the SMD package; for through-hole heatsinking look at the T (TO-220) codes. Evidence: TI/National LM2596 datasheet and distributor listings confirm 3.3 V fixed, 3 A, 4.5-40 V, 150 kHz and TO-263. Match the full LM2596S-3.3/NOPB code for voltage, package and lead-free packing. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

LM2596S-ADJ/NOPB is a Texas Instruments SIMPLE SWITCHER 3 A step-down regulator in TO-263-5 (DDPAK), tube — for general-purpose buck conversion: appliances, industrial power and pre-regulation. 3 A switching with only a handful of external components is the selection point: the classic easy-to-design buck. Selection advice: the S suffix denotes the TO-263 surface-mount package — for through-hole, the TO-220 LM2596T variants are the siblings; ADJ is the adjustable 1.2 V to 37 V version — for fixed 3.3 V, 5 V or 12 V rails, the fixed versions need no feedback divider; the 150 kHz switching keeps design simple but needs a larger inductor than modern MHz bucks — pick it for simplicity and proven supply, not for smallest size. 4.5 V to 40 V input. TI lists this part as ACTIVE. Parameters verified against the TI official product page. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

LM2596SX-5.0/NOPB is a Texas Instruments LM2596 SIMPLE SWITCHER fixed 5 V step-down (buck) regulator — 3 A, 4.5 to 40 V input, 150 kHz fixed-frequency internal oscillator, in the 5-lead TO-263 surface-mount package, tape-and-reel packing (X suffix), NOPB lead-free, operating -40 to +125 °C. The fixed 5 V version is the selection point: the standard 12 V or 24 V bus down to a 5 V logic rail with no feedback divider — four external components per the datasheet circuit and no resistor-tolerance error on the output. Selection advice: the X suffix is the procurement decision — reel packing for automated SMT lines and volume builds versus the tube-packed S codes for prototyping; do not mix packing codes on one production BOM. Electrically the same family cautions apply as the tube versions: 150 kHz means a larger inductor than modern switchers, non-synchronous so light-load efficiency trails modern synchronous bucks, with thermal shutdown, current limiting and TTL shutdown built in. Choose the fixed 5 V code when the rail is known; the adjustable LM2596S-ADJ only when the voltage must be trimmable. Evidence: TI/National LM2596 datasheet and distributor listings confirm 5 V fixed, 3 A, 4.5-40 V, 150 kHz, TO-263 and reel packing. Match the full LM2596SX-5.0/NOPB code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TPS54240DGQR is a Texas Instruments 42 V, 2.5 A step-down regulator in 10-pin HVSSOP PowerPAD — for space-constrained wide-input supplies: smart meters, industrial sensors and automotive modules where the 5 A class is oversized. 200 mΩ high-side MOSFET, 138 µA operating quiescent current, 100 kHz to 2.5 MHz switching range with external sync, and power-good output for sequencing. Ranked #18 on the 创芯指数 March 2026 search-surge chart with a 730.00% month-on-month search increase. Selection advice: at 2.5 A this is the right-sized sibling of the 5 A TPS54560B — specify the DGQR reel code for the HVSSOP-10 footprint; for 60 V-tolerant designs the TPS54360 is the higher-voltage sibling. The adjustable UVLO suits battery-backed systems with wide discharge curves. Parameters verified against Texas Instruments documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TPS5430DDA is a Texas Instruments 3 A step-down (buck) converter, 5.5 to 36 V input, 1.221 to 31 V adjustable output, fixed 500 kHz, in the 8-pin HSOP PowerPAD package (DDA = tube packing) — the classic 24 V-bus to 5 V/3.3 V workhorse for industrial controls, PLCs and communication power. The 36 V input ceiling plus internal 110 mΩ high-side MOSFET is the selection point: it regulates 24 V nominal rails (with surge headroom) down to logic voltages with few external parts, using voltage-mode control with input feed-forward and internal compensation to simplify loop design. Selection advice: the DDA suffix is the tube-packed HSOP-8 PowerPAD; order TPS5430DDAR for tape and reel — same die, different packing, so match the suffix to your SMT line. This is a non-synchronous buck, so the external Schottky diode (e.g. B340A in the TI reference design) is mandatory, not optional; and the exposed PowerPAD must be soldered to the PCB for rated thermal performance. For lower-voltage rails compare TPS5431 (23 V max input); for a synchronous alternative without the diode, look at a different family. Parameters verified against TI datasheet SLVS632. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TPS5430DDAR is a 3 A step-down switching regulator from Texas Instruments in an 8-pin SO PowerPAD package, for distributed power architectures — point-of-load rails derived from a higher-voltage bus. Its advantage over linear regulation is efficiency: at 3 A output, a switcher wastes far less power as heat, which shrinks heatsinking and improves system reliability. Selection advice: the DDA suffix denotes the thermally enhanced PowerPAD package and R tape-and-reel packing — thermal performance depends on the PowerPAD soldered to copper, so follow the datasheet layout guidance. Switching regulators need their inductor and compensation network designed around the chip; confirm your input/output voltage and current requirements against the datasheet before substituting a different regulator.

TPS62160DSGR is a Texas Instruments DCS-Control synchronous step-down converter in 2 x 2 mm WSON-8, tape and reel — for high-density power rails: battery systems and 12 V intermediate rails. 2.25 MHz switching with 17 µA quiescent current is the selection point: tiny inductors plus high light-load efficiency. Selection advice: the DSGR suffix denotes the 2 x 2 mm WSON-8 package — for the 3 x 3 mm VSSOP-8, the DGK variants are the siblings; TI documents pin-to-pin compatibility with the TPS62170 and TPS62125 — verify against the datasheet before substituting; the adjustable 0.9 V to 6 V version suits non-standard rails, fixed versions exist for standard rails. 3 V to 17 V input, up to 1 A output. TI lists this part as ACTIVE. Parameters verified against the TI official product page. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TPS54331DDA is a Texas Instruments TPS54331 3 A SWIFT step-down converter in HSOIC-8 with PowerPAD, tube packaging — 3.5 V to 28 V input, adjustable output down to 0.8 V, fixed 570 kHz switching, integrated 80 milliohm high-side MOSFET, pulse-skipping Eco-mode for light-load efficiency, adjustable soft-start and programmable UVLO, −40 °C to +150 °C junction. The DDA code is the selection point: the thermally enhanced PowerPAD package on tube — the exposed die pad solders to board copper and is the difference between a 3 A converter that survives a sealed enclosure and one that thermally shuts down. Selection advice: pick the DDA for prototypes and pre-production where the thermal design is still being proven — same footprint as the production DDAR reel code, so the layout carries over unchanged. Against the standard SOIC-8 TPS54331D, the PowerPAD version is the safe pick whenever full-current operation meets limited airflow. Non-synchronous: an external catch diode is required. Evidence: TI TPS54331 product page confirms the HSOIC PowerPAD option, 3.5–28 V, 3 A and 570 kHz. Match the full TPS54331DDA code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TPS54331DDAR is a Texas Instruments TPS54331 3 A SWIFT step-down converter in HSOIC-8 with PowerPAD, 2500-piece tape and reel — 3.5 V to 28 V input, adjustable output down to 0.8 V, fixed 570 kHz switching, integrated 80 milliohm high-side MOSFET, pulse-skipping Eco-mode for light-load efficiency, adjustable soft-start and programmable UVLO, −40 °C to +150 °C junction. The DDAR code is the selection point: the PowerPAD package on 2500-piece reel for volume production — the exposed pad plus pick-and-place assembly is the combination that ships 3 A rails reliably at scale. Selection advice: qualify the thermal design on the tube TPS54331DDA, then move to the DDAR reel for production with zero layout change — same footprint, same pinout. Against the standard SOIC-8 TPS54331D, choose the PowerPAD codes whenever the converter runs near full current; against the tube DDA, the R suffix is purely the production packing. Non-synchronous: an external catch diode is required. Evidence: TI TPS54331 product page and distributor listings confirm HSOIC PowerPAD, 2500-piece reel, 3.5–28 V and 3 A. Match the full TPS54331DDAR code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.
