Pin Description

Pin Number

Pin Name

Pin Function

1

VCC

Bias Supply Input. Apply 3V-6V to this input for internal bias to the controller.

2

EN

Enable (Input): CMOS compatible input. Logic high = enable, logic low = shutdown.

enable pin. Floating this pin causes the enable to be in an undetermined state.

3

VDDQ

Input Supply Voltage.

4

VREF

Reference voltage equal to half of VDDQ. For internal use only.

5

GND

Ground.

6

FB

Feedback input to the internal error amplifier.

7

COMP

Compensation (Output):

Connect a capacitor and resistor from COMP pin to

feedback pin for compensation of the internal control loop.

8

LD

Low-side drive: Connects to the Gate of the external low-side MOSFET.

9

HD

High-side drive: Connects to the Gate of the external high-side MOSFET.

10

NC

Not internally connected.
