GL8258N

Preliminary GL8258N/58AN Primary Feedback PWM Controller for Flyback Application Features Primary Sensing for Constant-Voltage(CV) and Constant-Current(CC) Regulation Pulse by Pulse Current Limiting (OCP) Low Start-Up Current (6uA) Fixed Frequency for Driving Power MOS VCC Over-Voltage Protection Output Over-Voltage Protection Cable Compensation for CV regulation (GL8258AN only) SOT-26 Package with Few External Components Needed Description The GL8258N/58AN is an excellent primary side feedback control PWM IC. It’s integrated constant voltage (CV) and constant current (CC) regulation functions. While it operates on CV mode, it acts as a voltage source. While it operates on CC mode, it acts as a current source. 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, greenmode power-saving operation, VCC over-voltage protection, and FB pin abnormal conditions sensing Application LED Lighting to prevent the circuit being damaged from the abnormal conditions.
