Product Overview
The TPS62913 is a Texas Instruments synchronous buck converter in the TPS6291x device family. It is specified for Power_Management use with a 3 A output current rating and recommended operating ranges of 3.0-17 V input and 0.8-5.5 V output. The device uses fixed-frequency peak current mode control with selectable 2.2 MHz or 1 MHz operation and external synchronization ranges tied to each setting.
Noise and regulation parameters include ±1% output voltage accuracy, less than 20 µVrms low-frequency output noise from 100 Hz to 100 kHz, less than 10 µVrms output ripple after a ferrite bead filter, and more than 65 dB PSRR up to 100 kHz. Electrical-characteristic conditions list PSRR examples of 65 dB at 12 V input and 70 dB at 5 V input.
The package is a 10-pin QFN RPU, 2.0 mm x 2.0 mm with 0.5-mm pitch. Recommended external components include 5 µF minimum effective input capacitance, 2.2 µH or 4.7 µH nominal output inductance, and 40-200 µF effective total output capacitance. Datasheet limits cover -40 to 150 °C operating junction temperature, thermal shutdown, power-good behavior, enable thresholds, and absolute maximum pin ratings.
