GR8835A - Green-Mode PWM Controller

General 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.

Key Features

  • Current mode PWM Very low startup current Under-voltage lockout (UVLO) Non-audible-noise green-mode control Programmable switching frequency Cycle-by-cycle peak current limiting Internal leading-edge blanking Internal slope compensation Internal 4ms soft start (Fs=65KHz) VCC over voltage clamp Gate output voltage clamp Soft driving for reducing EMI Over-voltage protection (OVP) on VCC Pin Over-load protection (OLP) Over-current protection (OCP) on CS Pin 300mA driving capability.
