UNISONIC TECHNOLOGIES CO., LTD
UM606
LINEAR INTEGRATED CIRCUIT
CONSTANT VOLTAGE AND CONSTANT CURRENT CONTROLLER
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
