TPS54331D

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.

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.

DRV8871DDAR is a brushed DC motor driver from Texas Instruments in an 8-pin SOIC package, with integrated current regulation — for small brushed-DC motors in appliances, toys and automation. Integrated current regulation is the selection point over basic H-bridges: it limits motor current without external sense resistors and comparators, protecting both the motor and the driver. Selection advice: the DDAR suffix denotes SOIC-8 on tape and reel — match the full code to your layout. Confirm your motor voltage and stall current against the datasheet ratings before substituting a different driver.

MC34063ADR is a Texas Instruments 1.5 A buck/boost/inverting switching regulator in SOIC-8 — the universal DC-DC workhorse: 3–40 V input, adjustable output, up to 100 kHz, 2% precision reference, short-circuit current limiting. Heat evidence: perennial high-demand part for power supply designs — one of the most second-sourced switching regulators ever made. Selection advice: the ADR code is SOIC-8 on reel — the same die ships in PDIP as MC34063AP; for automotive temperature range order the MC33063A variant. 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.

TPS54231DR is a Texas Instruments 28 V 2 A non-synchronous buck converter in SOIC-8 — for cost-sensitive 12/24 V to low-voltage rails: set-top boxes, industrial sensors and consumer power adapters. 3.5–28 V input, 0.8–25 V adjustable output, fixed 570 kHz switching, 75 µA typical operating current (1 µA shutdown), Eco-Mode. Heat evidence: high-volume buck converters remain allocation-sensitive as consumer and industrial demand overlaps — the TPS54231 is a staple for 2 A rails. Selection advice: fixed 570 kHz keeps the inductor small and the BOM simple — vs the TPS54360B choose this when 28 V headroom is enough and cost matters more than wide-input margin. 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.

TPS54331DR is a 3 A synchronous step-down converter from Texas Instruments in an 8-pin SOIC package — for industrial power supplies. Synchronous rectification is the selection point over nonsynchronous bucks: the integrated low-side MOSFET replaces the external Schottky diode, raising efficiency and cutting component count. Selection advice: the DR suffix denotes SOIC-8 on tape and reel — match the full code to your layout. Confirm your input/output voltage and load current against the datasheet, and follow the layout guidance for the switching node.

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.
