Pin Description

Pin

Name

Function

1-2

SW

Switched-node connection, which is connected with the source of the internal high-side

MOSFET.

3-5

V

IN

Main power supply input pin. Connected to the drain of the high-side MOSFET.

6V

CB

Bootstrap capacitor connection for high-side gate drive.

7AV

IN

Input voltage for control and driver circuits.

8

SD(SS)

Shutdown and Soft-start control pin. Pulling this pin below 0.3V shuts off the regulator. A

capacitor connected from this pin to ground provides a control ramp of the input current.

Do not drive this pin with an external source or erroneous operation may result.

9

FB

Output voltage feedback input. Connected to the output voltage.

10

COMP

Compensation network connection. Connected to the output of the voltage error amplifier.

11

PGOOD

A constant monitor on the output voltage. PGOOD will go low if the output voltage

exceeds 110% or goes below 80% of its nominal.

12

LDELAY

A capacitor between this pin to ground sets the delay from the output voltage reaches

80% of its nominal to when the undervoltage latch protection is enabled and PGOOD pin

goes low.

13

AGND

Low-noise analog ground.

14-16

PGND

Power ground.
