TPS61071TDDCRQ1

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.
