8.5W Dual Output (5V/12V) Universal Input AC/DC Isolated Flyback Reference Design with PSR

Overview

TopologyFlyback Converter
Input voltage90-265 V
Output 15 V / 0.5 A
Output 212 V / 0.5 A
IC revisionE1

Description

The TIDA-00618 reference design is a Primary Side Regulation switcher which provides isolated dual outputs, 5V and 12V rails, with DC stacking of the secondaries to provide output voltage regulation that is equivalent to op-to-coupler based solution.Low system parts count and built in advanced protection features result in a cost-effective solution with an average efficiency of nearly 75% at 230V

Features

  • Isolated 5V and 12V output at 500mA maximum
  • Conducted EMI compliant
  • 100ms typical start-up time
  • Primary side control eliminates need for op-to coupler
  • Input under & Output over voltage protection
  • Primary over current protection
  • Controlled start up and restart after fault Protection
