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.
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
