High Voltage Ratio Vout/Vin, 2W Boost Converter Reference Design

PMP10077

Design files

Overview

When high voltage ratio between output and input is required, it's always difficult to choose the right topology. In this case, the most-simple Boost has been selected due to cost reasons. The converter runs in DCM mode therefore avoiding the Trr of the diode and shows good efficiency.

Features
  • Good efficiency values despite the high Vout/Vin ratio
  • Simple and low cost solution
