Overview

The LM5185EVM-SIO evaluation module (EVM) demonstrates the features and performance of the LM5185-Q1, Primary-Side Regulated (PSR) flyback controller. It samples the voltage of the transformer's primary winding to achieve tight output regulation without using the opto-coupler or tertiary bias winding. The input voltage range is 20 V to 60 V, and the output is 16.4 V with a rated load of 1 A.

Features
  • 20 V to 60 V input voltage range
  • 16.4 V output voltage
  • 1 A rated load current
  • Maximum switching frequency 350 kHz
  • Peak efficiency > 90%
