Übersicht

Description

TPS62873QWRXSRQ1 is Texas Instruments’ ultra-low-power step-down DC-DC converter (buck regulator) in a compact package. It’s intended for battery-powered and space-constrained electronics (wearables, IoT sensors, portable devices) that need long battery life and efficient regulation. Key features typically include very low quiescent current, high efficiency across a broad load range, enable control, soft-start, and protection features (short-circuit, over-temperature, undervoltage). The device provides a regulated output from a higher input voltage through an external feedback network (with fixed or adjustable output variants depending on the part). The QWRXSRQ1 suffix identifies the specific packaging, RoHS compliance, and tape-and-reel variant. For exact electrical characteristics, pinout, and application notes, consult the TI TPS62873QWRXSRQ1 datasheet and product page.

Features

Here are the key features of TPS62873QWRXSRQ1 (concise):
- Automotive-grade (AEC-Q100) device with extended temperature range
- Wide input voltage range: suitable for battery and Li‑ion supplies
- High efficiency with optimized operation across load ranges
- Power Save Mode for ultra-low-load efficiency
- Enable pin for controlled shutdown
- Built-in protections: soft-start, current limit, thermal shutdown
- Small, rugged package suitable for compact designs
- Qualified/reliability tested for automotive applications
Note: For exact electrical specs (input range, output options, efficiency curves, and package details), please refer to the latest TI datasheet.

Package

QFN-16 package, 3×3 mm (TPS62873 in the QWR variant with wettable flanks).

Pinout

Pin count: 8 pins (WQFN package) with an exposed ground pad.
Function: TPS62873QWRXSRQ1 is a high-efficiency step-down DC-DC buck regulator. Key pins include VIN (input), GND (ground), EN (enable), SW (switch node), FB (feedback), BYP (bypass for compensation), plus two additional control/diagnostic pins depending on variant (e.g., power-good/soft-start). For exact pin names and layout, refer to the datasheet for the QWRXSRQ1 variant.

Manufacturer

- Manufacturer: Texas Instruments Incorporated (TI).
- Company type: American multinational semiconductor company that designs and manufactures analog and embedded processing integrated circuits.

Application

TPS62873QWRXSRQ1 is a high-efficiency, ultra-low quiescent current buck regulator for battery-powered electronics. Typical application areas: wearable devices (fitness trackers, smartwatches), battery-powered IoT sensors and gateways, portable consumer electronics, mobile accessories, medical wearables, and automotive/industrial sensors needing efficient, compact power management.
