Pin Description
Symbol Function
GND
Ground and reference pin
RETURN1 Return line of the external unit, internally connected to GND via a line-protection transistor
OUT1 Voltage-stabilized supply output and current-modulation input
VS
Supply voltage of the IC
OUT2 Voltage-stabilized supply output and current-modulation input
SC
Smooth time constant for slow voltage change at both OUT pins
RETURN2 Return line of the external unit, internally connected to GND via a line-protection transistor
GND
Ground and reference pin
ENABLE2
Controls OUT1 voltage
ENABLE1 High = OUT1 active, ENABLE1 Low or open = OUT1 switched off
CLL2
Current logic level output (low at high OUT2 current, monitoring via OCM2)
OCM2 Analog current output, representing 1/10 current of OUT2
OCM1 Analog current output, representing 1/10 current of OUT1
CLL1
Current logic level output (low at high OUT1 current, monitoring via OCM1)
ENABLE1
Controls OUT2 voltage
ENABLE2 High = OUT2 active, ENABLE1 Low or open = OUT2 switched off
GND
Ground and reference pin
