Description

The LR5810 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 blanking, over load protection and fault condition

auto-restart. They are ideal low power AC/DC adapter/charger solution for portable devices,

Features

• 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 protection): Typ.28 V

• Operation Frequency: Typ.54KHZ(VDD=21V)

• Output Driver Ability: Typ.15 mA

• OLP(over load protection)

• Universal AC input range

• Constant voltage and constant current

• Small SOT-23-6 and SOP-8 package.

Applications

? AC/DC adapter/charger for cell/cordless phones, digital cameras, MP3/portable audio devices

etc

• LED Lighting

• Replacements for linear transformers and RCC SMTPS
