SM7525 Datasheet (Sunmoon) - Primary Side Feedback Controlling Switch

SM7525, Primary Side Feedback Controlling Switch

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 windi
