DESCRIPTION
The GR8876 is a highly-integrated, low startup current, current mode PWM controller with green-mode function and high-voltage start up circuit. A high-voltage current source supplies the start up current and the traditional start up resistance can be saved in order to limit the power cost. The controller also includes the leading-edge blanking of the current sensing, internal slope compensation and cycle-by-cycle peak current limiting.
