TPS627431YFPR is a compact 400 mA buck regulator for low-power rails from 2.15 V to 5.5 V inputs, with fixed selectable output settings from 1.3 V to 3.1 V.

Best for

  • Battery-powered low-power MCU rails
  • Wearable and sensor systems
  • Bluetooth Low Energy and RF-powered rails

Avoid if

  • A continuously adjustable output voltage is required
  • Input voltage can remain too close to the selected output voltage at required load
  • The PCB process cannot support 0.4 mm-pitch DSBGA assembly

Check before use

  • Program all VSEL pins; they must be terminated.
  • Connect VOS directly to the output capacitor with a short, quiet trace.
  • Place the input capacitor close to VIN and GND.
  • Confirm output-current derating when VIN approaches VOUT.
