Features Low Start-Up Current (<2uA) Multi-Mode Operation CCM @ Heavy Load and Low Line QR-Like Operation @ Medium Load Green mode with Valley Skip at Light Load Burst Mode at No Load Accurate Over Current Protection Adjustment OVP on QRD Pin Output Short Protection Soft Driver 8ms Soft-start OVP (Over Voltage Protection) on VCC Pin On Chip OTP Protection SOT-26 Package with Few External Components Needed Description The GR1230R is a high performance multi-mode (QR/CCM) PWM controller for flyback converter. It minimizes the components counts and is available in a tiny SOT-26 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 SMPS Power Supply
