This page provides the datasheet information for the UM612A, a member of the UM612 SPS SECONDARY-SIDE CC/CV CONTROLLER family.

Datasheet Summary

Description

The UTC UM612/A is a secondary-side CC/CV controller for SPS 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.

UNISONIC TECHNOLOGIES CO., LTD UM612/A LINEAR INTEGRATED CIRCUIT SPS SECONDARY-SIDE CC/CV CONTROLLER  DESCRIPTION The UTC UM612/A is a secondary-side CC/CV controller for SPS 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 the CV control loop and regulate the output current by the CC control loop at the same time. The transformer secondary-side output voltage can be monitored by the FB pin voltage. The sensed FB pin voltage is compared with the 2.5V internal reference. When the FB pin voltage is higher than 2.
