Preliminary GR9230RK Multi-Mode PWM Power Switch with Integrated Protections Features Description Built-in 650V Power MOSFET The GR9230RK 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 SOP-7 QR-Like Operation Medium Load and DIP-8 package. Those make it an ideal design Green mode with Valley Skip at Light Load for low cost application. It provides functions of low Burst Mode at No Load startup current, green- mode power-saving Accurate Over Current Protection operation, VCC over-voltage protection, and QRD Adjustment OVP on QRD Pin pin abnormal conditions sensing to prevent the Output Short Protection circuit being damaged from the abnormal Soft Driver conditions. 8ms Soft-start OVP (Over Voltage Protection) on VCC Pin Applications On Chip OTP Protection Switching AC/DC power adapter SOP-7 and DIP-8 Package with Few External SMPS Power Supply Components Needed Typical Application Information EMI FILTER DRAIN VCC DRAIN QRD CS GND GND COMP GR9230RK 2015.06.
