PIN #

NAME

DESCRIPTION

1

EN

Enable pin for the IC. Drive this pin to high to enable the part, low to disable.

2

GND

Ground

3

SW

Inductor Connection. Connect an inductor Between SW and the regulator output.

4

IN

Supply Voltage. Short to PIN. Bypass with a 10μF ceramic capacitor to GND

5

FB

Feedback Input. Connect an external

resistor divider from the output to FB and

GND to set the output to a voltage between 0.6V and VIN

DESCRIPTION

1

PGND

Power Ground. Bypass with a 10μF ceramic capacitor to PVIN

2

SW

Inductor

Connection. Connect an inductor

Between SW and the regulator output.

3

AGND

Analog Ground, Connect to PGND

4

FB

Feedback Input. Connect an external

resistor divider from the output to FB and

GND to set the output to a voltage between 0.6V and VIN

5

EN

Enable pin for the IC. Drive this pin to high to enable the part, low to disable.

6

MODE

When forced high, the device operates in fixed frequency PWM mode. When forced

low, it enables the Power Save Mode with automatic transition from PFM mode to

fixed frequency PWM mode. This pin must be terminated.

7

AVIN

Analog Power. Short externally to PVIN

8

PVIN

Supply Voltage. Bypass with a 10μF ceramic capacitor to PGND
