PMP4408.1, Offline AC/DC 120W Multi-Output Flyback Power Supply Reference Design

PMP4408.1, Offline AC/DC 120W Multi-Output Flyback Power Supply Reference Design. 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 down-stream 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
