Description

The GR9230HK is integrates a high performance multi-mode (QR/CCM) PWM controller and a high voltage power MOSFET of 650V. It minimizes the components counts and is available in a tiny DIP-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 QRD pin abnormal conditions sensing to prevent the circuit being damaged from the abnormal conditions.


Applications

Switching AC/DC power adapter
