DESCRIPTION

The UTC UM606 for a constant voltage/constant current mode

SMPS (switch mode power supplies) application which is a highly

integrated solution, it contains one 1.21V voltage reference with ±1%

accuracy, one current sensing circuit and two operational amplifiers.

The UTC UM606 is an ideal voltage controller for use in adapters

and battery chargers because the voltage reference it’s combining

with one operational amplifier. And the UTC UM606  is  an ideal

current limiter for output low side current sensing because the other

low voltage reference is combining with the other operational

amplifier.

FEATURES

*Constant Voltage and Constant Current Control

*Precision Internal Voltage Reference

*Few External Components

*Easy Compensation
