FUNCTION

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

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

Current Limitation Reference Input

Ground

Current Limitation Loop Input, connected to the sense resistor

Output pin common to the voltage regulation and current limitation loops. This

output can drive the primary side (LED) of an optocoupler

Voltage Regulation Loop Input

Power Supply Input (4.5 ~ 32VDC)
