TERMINAL FUNCTIONS
TERMINAL
DESCRIPTION
NAME
NO.
BOOT
1
Boost capacitor for the high-side FET gate driver. Connect 0.01-
F low ESR capacitor from BOOT pin to PH pin.
NC
2, 3
Not connected internally
VSENSE
4
Feedback voltage for the regulator. Connect to output voltage divider.
ENA
5
On/off control. Below 0.5 V, the device stops switching. Float the pin to enable.
GND
6
Ground. Connect to thermal pad.
Input supply voltage. Bypass VIN pin to GND pin close to device package with a high-quality low-ESR ceramic
VIN
7
capacitor.
PH
8
Source of the high side power MOSFET. Connected to external inductor and diode.
PowerPAD
9
GND pin must be connected to the exposed pad for proper operation.
