1

SAS disable input: set this pin logic-low to turn on the device, high to turn off the

device. This pin is internally pulled down via 1 MΩ resistor.

SS5

7

Soft Start adjustment pin for the 5 V rail. A capacitor must be connected between

this pin and GND to program the output voltage slew-rate. Do not leave floating.

SS12

8

Soft-start adjustment pin for the 12 V rail. A capacitor must be connected between

this pin and GND to program the output voltage slew-rate. Do not leave floating.

IMON_5

6

5 V rail current monitor. Connect a resistor between this pin and GND.

IMON_12

2

12 V rail current monitor. Connect a resistor between this pin and GND.
