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.

TPS54331D is a Texas Instruments TPS54331 3 A SWIFT step-down converter in SOIC-8, 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 D code is the selection point: the standard SOIC-8 on tube for prototypes and low-volume builds — the same silicon as the thermally enhanced DDA/DDAR codes, without the PowerPAD. Selection advice: pick the D when the 3 A load has thermal headroom on standard copper; pick the DDA/DDAR PowerPAD versions when the converter runs near full current in a hot enclosure — the exposed pad drops junction temperature dramatically. Note it is non-synchronous (external catch diode required), unlike fully synchronous bucks. The adjustable 0.8 V feedback covers everything from sub-1 V core rails to 24 V industrial rails. Evidence: TI TPS54331 product page confirms 3.5–28 V, 3 A, 570 kHz, Eco-mode and the SOIC-8 package option. Match the full TPS54331D code.

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.

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. Parameters verified against TI documentation. State quantity, packing and date-code requirements in your RFQ; we reconfirm the offered lot before quotation and reply within 24 hours.

DRV8256PPWPR is a Texas Instruments single H-bridge motor driver with integrated current sense and smart-tune technology — for industrial brushed-DC drives: 4.5-V to 48-V supply, 6.4-A peak output, 165-mΩ RDS(ON), and an internal current-mirror sense architecture that removes the power shunt resistor. The selection point is the inrush control: the driver regulates motor startup current automatically, protecting 24-V and 48-V rails from stall-current collapse — plus spread-spectrum clocking for low EMI in noise-sensitive cabinets. Selection advice: the PPWPR suffix is the HTSSOP-28 tape-and-reel orderable — the E variant (DRV8256EPWPR) uses EN/IN control while the P variant uses PH/EN, so match the control interface to your MCU firmware; for the compact 4x4-mm VQFN specify the RGER variant. TI lists this as Active in production. Parameters verified against TI documentation.
