Description

This reference design is an auxiliary power supply with 24-V, 2-A output. The line and load regulation of the power supply is designed to be within 1% using secondary side regulator UCC28740. All components are on the toplayer and the size is the industrial standard half-brick dimension.

Features
  • Valley switching operation and VS balance synchronous rectifier flyback
  • Secondary-side feedback improve load regulation
  • All components on the toplayer simplify adding heatsink on the bottom side
  • Integrated input OVP, UVLO, and output OVP, OCP, SCP improve system reliability
