Description

The PMP4408 is a universal AC input, 120W flyback converter reference design. The LM5023 Quasi Resonant Flyback converter was chosen to get 2 high-efficiency isolated outputs. Additionally a downstream Buck converter, the TPS5402 enables 2 high-efficiency non-isolated outputs. The QR Flyback design implements Valley switching for high-efficiency and full protection features such as output short circuit and output overvoltage.

Features
  • Good cross regulation
  • Valley switching for high efficiency
  • Output OVP, OCP and Short Circuit Protection
  • Input brown-out
  • Average efficiency is high
  • Size 92mm(L) x 95mm(W) x 30mm(H)
