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.
