概述
Description
TPS61071TDDCRQ1 is TI’s small boost- DC-DC converter from the TPS61071 family. It’s designed for battery-powered, portable applications that need to raise a low battery voltage (typical single-cell Li‑ion/NiMH range) to a higher, stable output for peripherals and microcontrollers.
Key points:
- Boost regulator with external resistor set for a configurable output voltage (e.g., ~1.8–5.0 V range, depending on circuit).
- Optimized for high efficiency and long battery life; suitable for wearables, IoT sensors, and compact electronics.
- Includes protections (overcurrent/short-circuit, thermal) and a shutdown/enable pin to conserve power.
- Small package suitable for hand- or machine-assembly; “RQ1” indicates a tape-and-reel packaging variant.
- Typical switching frequencies and exact voltage ranges are specified in the datasheet.
For precise electrical specs, pinout, and packaging details, refer to the TPS61071 datasheet and product page.
