synchronous boost converter5.25 V output3.8 MHzDSBGAbattery powered

TPS61253EYFFR is a compact 5.25 V synchronous boost converter for single-cell battery-powered loads, with a 4.5 A typical switch valley current limit.

Best for

  • Single-cell lithium-ion battery boost rails
  • Compact 5.25 V loads
  • Applications needing selectable PFM, forced PWM, or ultrasonic operation

Avoid if

  • The input supply can remain below the required startup voltage
  • The board cannot support a 0.4 mm-pitch DSBGA assembly process
  • Required load current exceeds the validated operating capability at minimum input voltage

Check before use

  • Validate output regulation and thermal margin at the minimum battery voltage
  • Use an inductor with sufficient saturation-current margin
  • Account for MLCC DC-bias capacitance loss
  • Keep input capacitor, output capacitor, inductor, and IC close together
