GR8837H - Green-Mode PWM Controller

General Description

The GR8837H is a highly-integrated, low startup current, current mode PWM controller with green-mode function.

The integrated functions also include the leading-edge blanking of the current sensing, internal slope compensation, soft start OLP, and OCP.

Key Features

  • Current mode control Standby power below 100mW Under-voltage lockout (UVLO) Non-audible-noise green-mode control 100KHz 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 mode External OTP latch mode Over-load protection (OLP)-Auto recovery Mode Vcc OVP protection- Auto recovery Mode 300mA driving capability.
