NAME
FUNCTION
GND
Ground. Connect to the analog ground plane.
2
3
SS
Soft-Start. Connect a 0.1μF to 1μF ceramic capacitor from SS to GND. This capacitor
sets the soft-start period during startup. See the
Startup and Soft-Start
section. SS is
internally pulled to GND in shutdown.
3
4
COMP
Compensation. Connect to an external RC network to compensate the feedback loop.
See the
Compensation Design
section. COMP is internally pulled to GND in shutdown.
4
5
FB
Output Feedback. Connect to the center of a voltage-divider connected between OUT
and GND to set the output voltage. The FB threshold voltage is 0.8V.
5
6
EN
Enable. Drive EN logic high to enable the output, or drive logic low for shutdown.
Connect EN to IN for always-on operation.

PGND
Power Ground. Connect to the power ground plane and to the source of the low-side
external MOSFETs. Connect PGND to GND at a single point.
10
13
DL
Low-Side MOSFET Gate-Driver Output. Connect to the gate of the low-side external
MOSFETs. DL is pulled low in shutdown.
11
14
VL
Internal 5V Linear-Regulator Output. Connect a 1μF to 10μF ceramic capacitor from
VL to PGND. Connect VL to IN for V
IN
less than 5.5V. VL provides power for bias and
gate drive.

15
IN
Input Supply Voltage. IN is the input to the internal linear regulator. Connect VL to IN for
V
IN
less than 5.5V.
