Description
SM7523B is an off-line low power AC/DC switching power supply chip used in high-performance primary feedback control systems. It is designed to provide high precision constant current output over the full input voltage range, with an accuracy of less than ±5%. This chip eliminates the need for loop compensation and allows for cost reduction by eliminating the need for additional components such as optocouplers, TL431 and transformer auxiliary winding. It also features internal chip-by-cycle peak current limit, FB overvoltage protection, output open/short protection, and soft start power protection, all of which contribute to improved system reliability.
