Tiny SEPIC for Low Input Voltage Reference Design

PMP30296

Design files

Overview

This reference design is for input voltages from 1.8V to 9.6V and the output voltage is 3.3V with 200mA maximum. The LMR61428 works with constant duty-cycle (60%-70%) in burst mode.

Features
  • Low part count
  • Ideal for use with batteries (up to 6x AA cells)
  • No external compensation
  • High light load efficiency due to burst mode
  • Wide input voltage range (5:1)
