UM601A
LINEAR INTEGRATED CIRCUIT
VOLTAGE AND CURRENT CONTROLLER
DESCRIPTION
The UTC UM601A integrated circuit incorporates a high stability series band gap voltage reference, two ORed operational amplifiers and a current source.
This IC compares the DC voltage and the current level at the output of a switching power supply to an internal reference.
It provides a feedback through an optocoupler to the PWM controller IC in the primary side.
The controlled current generator can be used to modify the level of current limitation by offsetting the information coming from the current sensing resistor.
It can be used in voltage supervisors, every types of application requiring a precision voltage regulation and current limitation, over voltage protection, battery charger with a constant voltage and a limited output current.
