    EVB_SY22844

    The SY22844 is a PWM controller with several features to enhance performance of Buck converters. It integrates a MOSFET with 350V breakdown voltage to decrease physical volume. Both current and voltage regulation are achieved by the controller. It drives the Buck converter in the quasi-resonant mode to achieve higher efficiency and better EMI performance.
