F8 – F11, G8 – G11,
H8 – H11, J8 – J11,
K8 – K11, L8 – L11,

Switching Node - connection to the output
inductor.
SGND C1 – C3, D1 –D3, E1 –E3
Signal Ground.
ENABLE F1
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
10
A.
PRDY K1
Power Ready - This pin indicates the status of
ENABLE or V
DD
. This output will be driven
low when ENABLE is logic low or when V
DD
is less than 4.4V (typ.). When ENABLE is
logic high and V
DD
is greater than 4.4V
(typ.), this output is driven high. This output
has a 10mA source and 1mA sink capability.
PWM H1
TTL-level input signal to MOSFET drivers.
NC
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.
