GR8837H Description
Preliminary GR8837H Green-Mode PWM Controller with Hiccup Protection .
The GR8837H is a highly-integrated, low startup current, current mode PWM controller with green-mode function.
GR8837H 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 l
GR8837H Applications
* no load. The system should operate on burst mode,
Fig. 11 Gate Clamp/Soft Driving Driver is clamped to 13V by an internal clamping circuit. A totem pole gate driver is fine tuned to meet both EMI and efficiency requirement in low power application. An internal pull low circuit is activated after pr
