Bonjour, bienvenue chez Dasenic

This solution uses a 100W power adapter for USB PD3.0 Type-C applications as an example. The main controller uses Tongjia Semiconductor LD7798 PFC+PWM Combo IC, and is paired with the secondary side synchronous rectifier LD8526GL and LD6612 to realize the high-efficiency, low no-load standby power consumption PD charger in this case for charging/power supply.
