Function

Voltage Reference Output 1.24V, 10mA max. Do not short circuit

Voltage Regulation Loop input

Current Limitation Loop Input, connected to the sense resisto

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 enabled when the input voltage 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 32V DC)

Ground

4/13
