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.

Features ：
1.Topological structure support: Fly-back and low-cost BUCK- Boost 
2. Integrated 730V hybrid technology
3.Universal input voltage: 85Vac~265Vac 
4. Constant current precision less than ±5%
5.Universal voltage compatible with 1~5W
6.SunMoon patented no auxiliary winding of primary side feed-back control technology without coupler, 431 and other

   components.
