LD9535C Multi-Mode PWM Controller of Flyback

LD9535C Multi-Mode PWM Controller of Flyback

The LD9535C is built in a multi-mode PWM controller and integrated a 650V MOSFET. The multi-mode PWM controller which consists of Quasi-Resonant (QR) PWM control for light load condition and Continue Conduction Mode (CCM) for heavy load condition. Moreover, the QR controller not only gains the syste.
