概述

Description

TPS61071TDDCRQ1 is Texas Instruments’ high-efficiency synchronous buck DC-DC converter. It’s designed for battery-powered and portable electronics, providing a regulated output from a wide input source with minimal quiescent current and high efficiency across load.
Key points:
- Integrated high-side and low-side MOSFETs (no external Schottky diode required).
- Fixed-frequency PWM control with enable and soft-start.
- Protects against overcurrent and thermal shutdown.
- Undervoltage lockout and other protection features for robust operation.
- Output voltage set via external feedback network.
Typical applications include wearables, smartphones/tablets, IoT sensors, and other battery-powered devices needing a compact, efficient power solution.
Packaging note:
- TDDCRQ1 indicates the tape-and-reel option in an 8-pin package suitable for automated assembly.
If you want, I can pull the exact electrical specs (input range, output voltage options, switching frequency) and provide a quick comparison with closely related devices from the TPS6107x family.

Package

8-pin VSON package (3×3 mm).

Pinout

- Pin count: 8 pins (in a DDC/TDDC 3x3 mm package).
- Function: High-efficiency single-channel buck-boost DC-DC converter for battery-powered applications (can step input voltage up or down to a regulated output), with enable and protection features.

Manufacturer

- Manufacturer: Texas Instruments Incorporated (TI).
- What kind of company: An American multinational semiconductor company that designs and manufactures analog, mixed-signal, and embedded processing ICs, including power-management solutions.

Application

TPS61071TDDCRQ1 is a high‑efficiency buck DC‑DC regulator for portable, battery‑powered systems. Typical application areas include:
- Battery-powered consumer electronics (wearables, handheld meters, remotes)
- IoT/wireless sensors and gateways
- USB-powered devices and accessories
- Embedded/industrial instrumentation requiring a compact, efficient power rail
It’s suited for systems needing a compact regulator with good efficiency from a single‑cell to multi‑cell battery inputs.
