Preliminary GR1230RA-02 Multi-Mode PWM Controller with Integrated Protections multi-mode (QR/CCM) PWM controller for flyback Features Low Start-Up Current (<2uA) converter. It minimizes the components counts and Multi-Mode Operation is available in a tiny SOT-26 package. Those make CCM Heavy Load and Low Line it an ideal design for low cost application. It provides QR-Like Operation Medium Load functions of low startup current, green- mode Green mode with Valley Skip at Light Load power-saving operation, VCC over-voltage Burst Mode at No Load protection, and QRD pin abnormal conditions Accurate Over Current Protection sensing to prevent the circuit being damaged from Adjustment OVP on QRD Pin the abnormal conditions. Output Short Protection Soft Driver 8ms Soft-start Applications OVP (Over Voltage Protection) on Vcc Pin Switching AC/DC power adapter On Chip OTP Protection SMPS Power Supply SOT-26 Package with Few External Components Needed Description The GR1230RA-02 is a high performance Typical Application Information EMI FILTER VCC QRD GR1230RA-02 OUT GND COMP CS 2016.10.
