General Description
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.
