Design files

Overview

This reference design was designed for the 3 Phase E-meter application. It uses the UCC28600 quasi-resonant flyback controller to generate three 3KV isolated output rails from an extremely wide input source from 110VAC to 420VAC. The 3 output rails have independent protections to improve system reliability. The synchronous buck converter TPS560430 was used on the 12V 0.7A rail to generate a 0.1% output ripple voltage for post modules. The board size is 100mm(L)*50mm(W)*20mm(H).

Features
  • Wide input range from 110VAC to 420VAC
  • 3KV isolated output rails:12V/0.7A,12V/0.2A, 5V/0.2A
  • 0.1% output ripple for 12V 0.7A rail
  • Input OVP, independent output OCP and SCP feature for each rail
  • Size: 100(L)*50(W)*20mm(H)
