LINEAR INTEGRATED CIRCUIT
VOLTAGE AND CURRENT
CONTROLLER
 DESCRIPTION
The UTC UM601/A 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.
 FEATURES
* 1.24V Series Voltage Reference with 10mA Output Current and 1% Precision (UM601A)
* Two Operational Amplifiers with ORed Output and 1MHz Gain Bandwidth Product
* Built-In Current Generator with Enable / Disable Function
* 4.5 ~ 32V Supply Voltage Range
