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, green-
mode power-saving operation, VCC over-voltage
protection, and FB pin abnormal conditions sensing
to prevent the circuit being damaged from the
abnormal conditions.
