Description
PMP10407 is a quasi-resonant Flyback power suppy 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.
Features
- 85VAC to 265VAC, 50/60Hz input 5V/10A/50W output
- Fast transient response, <250mV deviation under 0A to 5A load step
- Over 84% average 4-point efficiency
- Over 79% efficiency at 10% load (5W)
- Less than 50mW standby power losses
- Protected against output short-circuits
