Description

1

IN

Input

Input supply to the buck regulator

2, 13

SW

Input

Inductor connection to switching node

3, 12

VSS

Input

Ground connection for the device

4, 14

NC

Input

Connect to VSS

5

EN1

Input

Digital input for chip enable, standby, and ship-mode. EN1 = 1 sets ship mode independent of

EN2. EN1=0, EN2 = 0 disables the buck converter and sets standby mode. EN1=0, EN2=1

6

EN2

Input

enables the buck converter. Do not leave either pin floating.

7

VRDIV

Output

Resistor divider biasing voltage

8

VIN_OK_SET

Input

Resistor divider input for VIN_OK threshold. Pull to VIN to disable. Do not leave pin floating.

9

VOUT_SET

Input

Resistor divider input for VOUT regulation level

10

VIN_OK

Output

Push-pull digital output for power good indicator for the input voltage. Pulled up to VIN pin.

11

OUT

Output

Step down (buck) regulator output

15

Thermal Pad

Input

Connect to VSS
