Silan Microelectronics current mode PWM controller SDH8322S

SDH8322S is a high-voltage start-up, current-mode PWM+PFM controller with built-in high-voltage MOSFET, suitable for Buck and Buck-Boost topologies. SDH8322S works with down-conversion under light load conditions to optimize the conversion efficiency under light load conditions. It operates in hiccup mode under extremely light load and no-load conditions, thereby effectively reducing the system's standby power consumption. SDH8322S integrates comprehensive abnormal state protection functions, including VDD under-voltage protection, VDD over-voltage protection, leading edge blanking, over-current protection, over-temperature protection, etc. SDH8322S can configure the output voltage through pins, and 12V/15V/18V output voltage is optional. SOP8 chip package supports maximum output current of 200mA in the full voltage range. This product has VDD overvoltage/undervoltage protection; output short circuit protection; overload protection; and overtemperature protection.
