UTC UM601/A
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.

FUNCTION
Voltage Reference Output 1.24V, 10mA max. Do not short circuit Voltage Regulation Loop Input Current Limitation Loop Input, connected to the sense resistor Current Limitation Reference Input Current source enable input. This current source can be used to offset the voltage measurement on the sense resistor and therefore to modify the charge current. The current source is enabled when the input volage on pin 2 is lower than 0.8V Output pin common to the voltage regulation and current limitation loops. This output can drive the primary side (LED) of an optocoupler Power Supply Input (4.5 to 32VDC) Ground
