Description
UNISONIC TECHNOLOGIES CO., LTD UM612/A LINEAR INTEGRATED CIRCUIT SPS SECONDARY-SIDE CC/CV CONTROLLER * .
The UTC UM612/A is a secondary-side CC/CV controller for SPS applications.
Features
* Secondary-Side Constant Voltage (CV) and Constant Current (CC) Control
* 4.75V to 50V Operation Voltage Range
* 0.6mA Quiescent Current
* ±1% Output Voltage Accuracy at Full Temperature Range
* Smooth Transition Between CC and CV Control Loops
* -5V Negative Voltage Toleran
Applications
* It integrates a Constant Current (CC) regulating amplifier, a Constant Voltage (CV) regulating amplifier, and 2 precision reference voltages. An internal 2.5V reference voltage is generated from VCC input power. The UTC UM612/A can be used to monitor the transformer secondary-side output voltage by
