LD7577 High Voltage Green-Mode PWM Controller

The LD7577 integrates several functions of protections, and EMI-improved solution in SOP-8 package. It minimizes the component counts and the circuit space. The device provides functions of low startup current, green-mode power-saving operation, leading-edge blanking of the current sensing and inter.
