GR8935M has the features of very low startup current and current mode PWM control with green-mode function at light load. These features enable the power supply to easily meet even the strictest power conservation requirements. The integrated functions of GR8935M also include the leading-edge blanking of the current sensing, internal slope compensation, cycle-by-cycle peak current limiting and soft start. OCP, OVP and OLP provide protection performance for fault conditions. To protect the power MOSFET from being damaged by supply over voltage, the internal Applications     Switching AC/DC power battery charger Digital camera Open-frame SMPS PDA power supply gate voltage of GR8935M is clamped at 18V. GR8935M improves the performance and reduces the cost of power supplies.
