DESCRIPTION

NAME

NO.

AGND

5

G

Analog ground should be electrically connected to GND close to the device.

BOOT

13

I

A bootstrap capacitor is required between BOOT and PH. If the voltage on this capacitor is below the

minimum required by the BOOT UVLO, the output is forced to switch off until the capacitor is refreshed.

COMP

7

O

Error amplifier output, and input to the output switch current comparator. Connect frequency

compensation components to this pin.

EN

15

I

Enable pin, internal pull-up current source. Pull below 1.2 V to disable. Float to enable. Can be used to

set the on/off threshold (adjust UVLO) with two additional resistors.

GND

3

G

Power ground. This pin should be electrically connected directly to the power pad under the device.

4

PH

10

O

The source of the internal high-side power MOSFET, and drain of the internal low-side (synchronous)

rectifier MOSFET.

11

12

PWRGD

14

O

An open drain output, asserts low if output voltage is low due to thermal shutdown, overcurrent,

over/under-voltage or EN shut down.

RT/CLK

8

I/O

Resistor Timing or External Clock input pin.

SS

9

I/O

Slow-start. An external capacitor connected to this pin sets the output voltage rise time. Soft

VIN

1

I

Input supply voltage, 2.95 V to 6 V.

2

16

VSENSE

6

I

Inverting node of the transconductance (gm) error amplifier.

Thermal Pad

G

GND pin should be connected to the exposed power pad for proper operation. This power pad should

be connected to any internal PCB ground plane using multiple vias for good thermal performance.
