FB
Feedback input pin. This pin is connected to the converter output. It
is used to set the output of the converter to regulate to the desired
value via an internal resistive divider. For an adjustable output, an
external resistive divider is connected to this pin on the 1V model.
2
5, 6
SGND
Signal ground. Connect the return of all small signal components to
this pin. (See board layout rules.)
3
7
EN
Enable input pin. A logic high enables the converter; a logic low
forces the AAT1151 into shutdown mode reducing the supply current
to less than 1
μ
A. The pin should not be left floating.
4
9
VCC
Bias supply. Supplies power for the internal circuitry. Connect to input
power via low pass filter with decoupling to SGND.
5
10, 11, 12
VP
Input supply voltage for the converter power stage. Must be closely
decoupled to PGND.
6, 7
13, 14, 15
LX
Connect inductor to these pins. Switching node internally connected
to the drain of both high- and low-side MOSFETs.
8
1, 2, 3
PGND
Main power ground return pin. Connect to the output and input
capacitor return. (See board layout rules.)
8, 16
NC
Not internally connected.
EP
Exposed paddle (bottom); connect to PGND directly beneath package.
