Pin #

Symbol

Function

Soft-start pin. A capacitor connected between this pin and GND determines the

soft-start time. If it is left floating the start-up time is about 300 µs

GND

Analog device ground

VDD

Internal LDO output and compensation pin. It provides a regulated 5 V auxiliary

output. This pin must be bypassed to GND via a 1 µF capacitor to ensure the correct

functionality of the device

IMON

Current monitor pin. A resistor (RMON) connected between this pin and GND

generates a voltage proportional to the output current. It is suggested to connect

a capacitor (CMON) in parallel to RMON to filter the monitor signal

Current feedback. A resistor (RCS) connected between this pin and GND provides

a feedback voltage for the current limit circuit and the overcurrent indicator (D_OC).

Do not connect any capacitance to this pin

CLREF

Current limit set-point pin. Connect a resistor to GND or force an external control

voltage to define the current limit set-point

EXP. PAD

VIN

Input voltage, internally connected to the power FET drain
