General Description

Features

SM7525 is a primary side feedback controlling power chip used

in off-line small power AC/DC switching power. It realizes high

precision (less than ±5%) constant current output under universal

input voltage. The circuit is no loop compensation and saves

opto-coupler, L431, transformer auxiliary winding and other

components to reduce the cost.

The circuit integrates cycle by cycle peak current limiting, FB

overvoltage protection, output open/short protection and soft-start,

which optimize the reliability.

Topological structure support:

Fly-back and low-cost BUCK-

Boost

Integrated 730V hybrid techno-

logy

Universal input voltage:

85Vac~265Vac

Constant current precision less

than ±5%

Universal voltage compatible

with 1~5W
