概述
Description
TPS627431YFPR is a Texas Instruments ultra-low quiescent current step-down (buck) regulator aimed at battery-powered devices. It belongs to the TPS6274x family and provides efficient DC-DC conversion from a higher input voltage to a regulated output, with options for fixed or adjustable outputs. Key features typically include very low standby/shutdown current, an enable/disable control, soft-start, and protections such as overcurrent and thermal shutdown. The YFPR suffix indicates a compact, tape-and-reel package designed for automated assembly. Applications include wearables, IoT sensors, portable electronics, and USB-powered devices where compact size and high efficiency are important. External components usually consist of an inductor, input and output capacitors, and a feedback network for adjustable variants. For exact voltage options, current capability, pinout, and package details, refer to the official TPS627431YFPR datasheet and TI product page.
Equivalent
I can help. Do you want pin‑compatible equivalents (same package/pinout) or any functionally similar regulator? Also share key specs: input range, desired output voltage, current rating, enable/power‑good, and preferred package. I’ll provide TI cross‑references and common distributor equivalents.
Pinout
- Pin count: 8 pins.
- Function: A single-output step-down (buck) DC-DC converter with integrated switching FETs (synchronous), typically featuring adjustable output via a feedback divider, enable, and soft-start for efficient voltage regulation in battery-powered designs.
