TPS56221DQPR

LM5164DDAR is a Texas Instruments 100 V input synchronous buck converter in SOIC-8, tape and reel — for industrial power supplies: 48 V bus step-down, PoE front ends and motor-drive auxiliaries. The 100 V input rating is the selection point: direct operation from high-voltage industrial buses that standard 60 V bucks cannot survive. Selection advice: the DDAR suffix denotes SOIC-8 in tape and reel for production — plan the external MOSFET, inductor and compensation network per TI's reference design; this is a controller-class part, not a module. For lower-voltage rails, cheaper integrated bucks save board space. Parameters verified against the TI official product page.

TLV62568DBVR is a Texas Instruments 1 A synchronous step-down buck converter in SOT-23-5 (DBV), tape-and-reel packing (R) — 2.5 V to 5.5 V input, adjustable output from 0.6 V up to VIN, up to 95% efficiency, 35 µA operating quiescent current, 1.5 MHz typical switching frequency, power-save mode for light-load efficiency, 100% duty cycle for lowest dropout, internal soft start, overcurrent and thermal-shutdown protection, −40 to +125 °C. The adjustable output with 100% duty cycle is the selection point: one part generates 1.2 V, 1.8 V, 3.3 V or any logic rail from a 5 V or Li-ion source with near-zero dropout, so the same footprint covers multiple rails across a board — a general-purpose point-of-load workhorse for set-top boxes, cameras, routers and disk drives. Selection advice: the DBV is the 5-pin SOT-23; the R suffix is tape and reel. The adjustable TLV62568 covers what the fixed-output members of the family do plus any custom rail — confirm the exact fixed-output code only if the BOM specifies one. TI lists TLV62568DBVR as Active. Evidence: TI TLV62568 datasheet (SLVSD89) and distributor listings confirm 1 A, 2.5–5.5 V, 0.6 V to VIN, SOT-23-5 and tape-and-reel packing. Match the full TLV62568DBVR code. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

TPS54302DDCR is a Texas Instruments 3 A synchronous buck converter in SOT-23-6, tape and reel — for compact point-of-load power: set-top boxes, printers and industrial I/O modules. 3 A from a SOT-23-6 is the selection point: unusual current density for general-purpose rails. Selection advice: the DDCR suffix denotes SOT-23-6 in tape and reel for production — follow TI's layout guidance closely, as thermal performance in this package depends on copper area; for higher currents, larger-package bucks are the step up. 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.

TPS560430XDBVR is a Texas Instruments 36V, 4A synchronous buck converter — for industrial and automotive power rails: 4A continuous output current, up to 36V input, synchronous rectification for high efficiency, SOT-23-6 package. The synchronous topology eliminates the external Schottky diode, so efficiency stays high across the load range while the BOM shrinks; the 36V input rating tolerates 24V industrial buses with margin for transients. Business impact: compact high-current bucks are the default choice for point-of-load regulation — the SOT-23-6 footprint fits where larger packages cannot, and TI availability keeps lead times manageable. Selection advice: the XDBVR code denotes SOT-23-6 on tape and reel — verify the switching frequency and compensation against the TI datasheet for your specific input/output combination. Ranked #11 on the hqbuy.com real-time hot list (2026-10-05). Parameters verified against Texas Instruments documentation.

The MIC28517T-E/PHA is a Microchip Technology 70 V, 8 A Hyper Speed Control synchronous buck regulator in a 32-pin 6 mm by 6 mm VQFN. Its 4.5 V to 70 V input range and adjustable 0.6 V to 32 V output with +/-1 percent feedback accuracy cover 12 V, 24 V and 48 V industrial and telecom rails from a single device, which consolidates inventory and simplifies platform power design. The adaptive on-time architecture gives ultra-fast transient response with small output capacitance, and a pin-selectable HyperLight Load or forced continuous-conduction mode keeps light-load efficiency high. Adjustable 270 kHz to 800 kHz switching, internal compensation, a built-in 5 V regulator, auxiliary bootstrap LDO, programmable current limit, hiccup short-circuit protection and thermal shutdown reduce external component count and protect the load, supporting safe start-up into a pre-biased output. It operates from -40C to +125C junction temperature. Selection advice: this variant carries the MODE pin for HLL versus CCM selection; if your design instead needs an externally adjustable soft-start time, choose its sibling MIC28516, which trades the MODE pin for a soft-start pin.

MP9943GQ-Z is a Monolithic Power Systems 3 A synchronous step-down converter, 4 to 36 V input, adjustable output from 0.8 V (792 mV feedback reference), 410 kHz, in a QFN-8 (3 × 3 mm) package — a compact point-of-load regulator for set-top boxes, networking gear and industrial modules. The synchronous architecture is the selection point: integrated high-side and low-side MOSFETs eliminate the external Schottky diode that non-synchronous bucks like the TPS5430 require, cutting BOM count and improving light-to-mid-load efficiency in the same 3 A class. Selection advice: the -Z suffix is MPS tape-and-reel packing (-P is tray/tube), so match the suffix to your assembly line; the EN pin gives simple sequencing/shutdown, the PG output supports power-good monitoring, and the SYNC pin accepts 200 kHz to 2.4 MHz external clocking for EMI-sensitive designs. Rated -40 to +125 °C junction. Do not confuse with the MP9943A variant (different feature set) — verify the exact MP9943GQ-Z code on the MPS datasheet. Parameters verified against the MPS MP9943 datasheet (Rev. 1.1) and distributor listings.

BQ25790 is Texas Instruments’ 5-A buck-boost battery charger for 1-to-4-cell Li-ion/Li-polymer packs in 2.9x3.3mm WCSP-56 — for USB-C PD charging where input voltage swings both above and below the battery voltage: the integrated buck-boost stage (all four switching FETs plus battery FET on-chip) automatically transitions between buck, boost and buck-boost without host intervention. 97% charging efficiency at 30 W, 3.6-to-24 V input range, NVDC power-path management that keeps the system alive even with a dead or removed battery, dual-input selector (USB, barrel, wireless, solar), D+/D- handshake for legacy fast-charge adapters, and I2C host control with an integrated ADC for telemetry. USB-C/PD compatible, -40 to +85°C. Selection advice: the WCSP package is the smallest footprint option — for easier assembly specify the QFN sibling BQ25792; for solar-input designs the BQ25798 variant adds MPPT. State cell count and input source mix in the RFQ so the offered lot is matched to the right charge profile. Parameters verified against Texas Instruments documentation.

BQ4050RSMR is a Texas Instruments battery fuel gauge — for 1-series Li-ion and Li-polymer packs: Impedance Track gauging algorithm for accurate state-of-charge reporting, integrated protection-friendly architecture, VQFN-12 package. The Impedance Track algorithm learns the cell characteristics over cycles, so reported capacity stays accurate as the battery ages — unlike simple coulomb counters that drift; accurate gauging prevents both unexpected shutdowns and over-conservative capacity margins. Business impact: reliable fuel gauging is a safety and user-experience feature — medical, industrial and consumer devices all depend on trustworthy remaining-capacity readings. Selection advice: the RSMR code denotes VQFN-12 on tape and reel — the BQ4050 targets single-cell packs — for multi-cell designs look at the BQ40 family stackable gauges; cell characterization data improves initial accuracy. Ranked #15 on the hqbuy.com real-time hot list (2026-10-05). Parameters verified against Texas Instruments documentation.

CSD95410RRB is a Texas Instruments 90 A peak NexFET smart power stage — for multiphase buck converters powering AI accelerators, FPGAs and datacenter ASICs: driver plus power MOSFETs in a 5x6 mm 41-pin VQFN-CLIP package, -40°C to +125°C. Integrated temperature-compensated bidirectional current sense and analog temperature output feed the controller's telemetry loop, while 1.75 MHz switching and ultra-low-inductance packaging push power density. This is the ACTIVE successor to the NRND CSD95490 — same footprint class, higher current rating. Selection advice: pair with TI multiphase controllers (TPS53681/TPS53688 on this site) per TI reference designs; the industry-common 5x6 mm footprint allows second-sourcing across vendors, but verify current-sense calibration against your controller.
