Description
The GR1230H is a high performance multi-mode (QR/CCM) PWM controller for flyback converter. It minimizes the ponents 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.
