Cxac85112p is a high-performance edge feedback control power switch chip applied to off-line low-power AC / DC switching power supply. It can achieve high-precision constant voltage

Cxac85112p is a high-performance edge feedback control power switch chip applied to off-line low-power AC / DC switching power supply. It can achieve high-precision constant voltage / constant current output within the full voltage input range, with accuracy less than ?3%, and can save optocoupler, TL431 and other components and reduce costs. In order to improve the reliability of the system, the chip integrates high voltage power switch, cycle by cycle peak current limit, hvdd over-voltage protection, hvdd under voltage protection, hvdd voltage clamp and other perfect protection functions
