Description
The GR8835A is a highly-integrated, low startup current, current mode PWM controller with Green-mode function. This function enables the power supply to easily meet even the strictest power conservation requirements. The integrated functions also include the leading-edge blanking of the current sensing, internal peak slope current pensation, cycle-by-cycle limiting and soft start. OLP, OCP and OVP provide...
