Pin Description Table

Pin Name

Ball Designator

Pin Function

VDD

A1 – A3, B1 – B3

Supply voltage for the internal circuitry.

VIN

A5 – A12, B5 – B12,

C5 - C10

Input voltage for the DC-DC converter.

PGND

C11, C12, D11, D12, E11,

E12, F6, F7, F12, G6, G7,

G12, H6, H7, H12, J6, J7, J12,

K5 – K7, K12, L5, L6, L12,

M5 – M7, M12

Power Ground - connection to the ground of

bulk and filter capacitors.

VSW

D5 – D10, E5 – E10,

F8 – F11, G8 – G11,

H8 – H11, J8 – J11,

K8 – K11, L8 – L11,

M8 – M11

Switching Node - connection to the output

inductor.

SGND

C1 – C3, D1 –D3, E1 –E3

Signal Ground.

ENABLE

When set to logic level high, internal

circuitry of the device is enabled. When set

to logic level low, the PRDY pin is forced

low, the Control and Sychronous switches are

turned off, and the supply current is less than

10µA.

PRDY

Power Ready - This pin indicates the status of

ENABLE or VDD. This output will be driven

low when ENABLE is logic low or when VDD

is less than 4.4V (typ.). When ENABLE is

logic high and VDD is greater than 4.4V

(typ.), this output is driven high. This output

has a 10mA source and 1mA sink capability.

PWM

TTL-level input signal to MOSFET drivers.

B4, C4, D4, E4, F2 – F4, G2 –

G4, H2 – H4, J1, J2 – J4, K3,

L1, L2, M1 – M4

This pin is not for electrical connection. It

should be attached only to dead copper.
