Preliminary GR9210RK Multi-Mode PWM Power Switch with Primary-Side Feedback Features Description Built-in 650V Power MOSFET The GR921 0RK integrates a high performance Low Start-Up Current (<2uA) primary side feedback PWM controller and a high Primary-Side Feedback Control with Multi-Mode voltage power MOSFET of 650V. It minimizes the Operation components counts and is available in a tiny CCM Heavy Load and Low Line SOP-8/DIP-8 package. Those make it an ideal QR-Like Operation Medium Load design for low cost application. It provides functions Green mode with Valley Skip at Light Load of low startup current, green- mode power-saving PFM Mode at No Load operation, VCC over-voltage protection, and FB pin Built-In Adjustable Load Regulation abnormal conditions sensing to prevent the circuit Compensation being damaged from the abnormal conditions.
