GR8837A - Green-Mode PWM Controller

General Description

The GR8837A 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 control Standby power below 100mW Under-voltage lockout (UVLO) Non-audible-noise green-mode control 65KHz switching frequency Internal leading-edge blanking Internal slope compensation Internal soft start Gate output voltage clamp Jitter and soft driving for reducing EMI External OVP Latch off mode External OTP Latch off mode Over-load protection (OLP)-Hiccup 300mA driving capability.
