CONSTANT VOLTAGE AND CONSTANT CURRENT CONTROLLER

AP4306

General Description

Features

The AP4306 is a highly integrated solution for a con-

stant voltage/constant current mode SMPS application.

Constant Voltage and Constant Current Control

Precision Internal Voltage Reference

Low External Component Count

Easy Compensation

Low Supply Current: 0.5mA

Current Control Loop Reference

A Version: 70mV

The AP4306 contains one 1.21V voltage reference,

one low voltage reference used in current sensing cir-

cuit and two operational amplifiers. The 1.21V voltage

reference, combined with one operational amplifier,

makes of an ideal voltage controller for use in adapters

and battery chargers. The low voltage reference, com-

bined with another operational amplifier, makes of an

ideal current limiter for output low side current sens-

ing.

B Version: 100mV

C Version: 150mV

Operating Temperature Range: -40 to 105^oC

Operating Supply Voltage: 2.5V to 18V

The AP4306 is fully compatible with AP4305 in

functionality and electrical characteristics except its

lower reference voltage for current control loop, thus

higher power efficiency in SMPS applications such as

low power charger can be realized with AP4306

compared to AP4305.

Applications

Adapters

Battery Chargers

The AP4306 is available in SOT-23-6 package.
