Wide-input voltage 6W buck converter reference design

PMP23397

Design files

Overview

This reference design uses UCC28C52 configured as a non-synchronous buck to convert a wide 20V to 150V input to a 12V output capable of 6W loading. The approach minimizes the number of parts required which enables a compact solution size.

Features
  • Compact 1-in by 1-in solution size with a 0.3-in max component height
  • Less than 100mV peak-to-peak ripple voltage
Output voltage options PMP23397.1
Vin (Min) (V) 20
Vin (Max) (V) 150
Vout (Nom) (V) 12
Iout (Max) (A) .5
Output Power (W) 6
Isolated/Non-Isolated Non-Isolated
Input Type AC
Topology Buck- Non Sync
