- PMP10407, Universal AC Input, 5V/10A/50W PSR Flyback Power Supply W/Rapid Load Transient Response Ref Design. The PMP10407 is a quasi-resonant Flyback power supply based on the UCC28730 primary side regulation (PSR) controller demonstrating the use of wake up device UCC24650 to achieve rapid load transient response from light load condition when the system is under low frequency operation. The elimination of optocoupler using PSR topology promises higher reliability and lower system cost. The design achieves less than 50mW standby power losses and over 86% efficiency at 25% load. The design also features UCC24610 synchronous rectification controller and demonstrates the use of UCC24650's ENS pin output to enforce diode rectification at light load conditions to reduce stand-by power losses
