GR9230HK Multi-Mode PWM Power Switch with Integrated Protections Features Description Built-in 650V Power MOSFET The GR9230HK is integrates a high performance Low Start-Up Current (<2uA) multi-mode (QR/CCM) PWM controller and a high Multi-Mode Operation voltage power MOSFET of 650V. It minimizes the CCM Heavy Load and Low Line components counts and is available in a tiny DIP-8 QR-Like Operation Medium Load package. Those make it an ideal design for low cost Green mode with Valley Skip at Light Load application. It provides functions of low startup Burst Mode at No Load current, green- mode power-saving operation, VCC Accurate Over Current Protection over-voltage protection, and QRD pin abnormal Adjustment OVP on QRD Pin conditions sensing to prevent the circuit being Output Short Protection damaged from the abnormal conditions.
