RM3253 ic equivalent, off line ac/dc switcher ic.
* Built-in 800V high voltage BJT and minimal external componets
* Low start-up current: Typ.15 μA Max.25 μA
* UVLO(under voltage lockout):Typ.12V start-up Typ.
The RM3253 series switcher ICs cost effectively replace all power supplies up to 5W output power based on
unregulated isolated linear transformer (50/60HZ). Unlike conventional PWM (pulse width modulation) controllers, they regulate the output voltag.
