GR8875N - grenergy

GR8875N Green-Mode PWM Controller

The GR8875N series is a highly-integrated, low startup current, current mode PWM controller with green-mode function, high-voltage start up circuit, and provides several protections such as OLP, OVP, and OCP for fault conditions. A high-voltage current source supplies the start up current and the traditional start up resistance can be saved in order to reduc.
