SM7523 datasheet

Description :

SM7523 is a high-performance primary-side feedback control power switch chip applied to off-line low-power AC/DC switching power supplies. It achieves high-precision constant current output within the full voltage input range, with an accuracy of less than ±5%, without loop compensation, and The system can save optocouplers, TL431 and transformer auxiliary windings and other components, reducing costs.

The chip integrates cycle-by-cycle peak current limit, FB overvoltage protection, output open/short circuit protection, and boot soft start protection functions to improve system reliability.
