Description

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)
