Pin #

Pin Name

Pin Function

1

VOUT

Output voltage sense input. Connect to the output at the load.

2

VCCA

Supply voltage input for the analog supply. Use a 10Ω /1μF RC filter from 5VSUS to VSSA.

3FB

Feedback input. Connect to a resistor divider located at the IC from VOUT to VSSA to

set the output voltage from 0.5V to VCCA.

4

PGD

Power Good open drain NMOS output. Goes high after a fixed clock cycle delay

(440 cycles) following power up.

5

NC

Not Connected.

6

VSSA

Ground reference for analog circuitry. Connect directly to thermal pad.

7

PGND

Power ground. Connect directly to thermal pad.

8

DL

Gate drive output for the low side MOSFET switch.

9

VDDP

+5V supply voltage input for the gate drivers. Decouple this pin with a 1μF ceramic

capacitor to PGND.

10

ILIM

Current limit input. Connect to drain of low-side MOSFET for RDS(on) sensing or the

source for resistor sensing through a threshold sensing resistor.

11

LX

Phase node (junction of top and bottom MOSFETs and the output inductor) connection.
