Description

The GR9210HL integrates a high performance primary side feedback PWM controller and a high voltage power MOSFET of 650V. It minimizes the components counts and is available in a tiny DIP-8, SOP-7 and SOP-8 package. Those make it an ideal design for low cost application. It provides functions of low startup current, green- mode power-saving operation, VCC over-voltage protection, and FB pin abnormal conditions sensing to prevent the circuit being damaged from the abnormal conditions.


Applications
