RM3253S Product details

Description

The RM3253S 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 voltage in a new method of off-time modulation control.The controller consists of a VCO (voltage control oscillator), Sense and logic circuit, VDD pin, under-voltage lockout circuit, protection for over-voltage, current limited circuit, leading edge blan.

Features

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.6V shut-down.
Low operating current:Typ.2 mA Max.5 mA.
LEB(leading edge blanking): Typ.300ns.
OVP(over voltage protecti.
