NAME
FUNCTION
1
COMP/EN
Compensation Input. Pull COMP/EN low with an open-collector or open-drain device to turn
off the output.
2
FB
Feedback Input. Connect a resistive-divider network to set V
OUT
. FB threshold is 0.8V.
3
V
CC
Internal Chip Supply. Connect V
CC
to VL through a 10
resistor. Bypass V
CC
to GND with at
least a 0.1μF ceramic capacitor.
4
V
IN
Power Supply for LDO Regulator for V
IN
> 5.5V, and Chip Supply for V
IN
< 5.5V. Bypass V
IN
with
at least a 1μF ceramic capacitor to GND.
5
VL
Output of Internal 5V LDO. Connect VL to V
IN
for V
IN
< 5.5V. Bypass VL with at least a 1μF ceramic
capacitor to GND.
6
DL
Low-Side External MOSFET Gate-Driver Output. DL swings from VL to GND.
7
GND
Ground and Negative Current-Sense Input
8
LX
Inductor Switching Node. LX is used for both current limit and the return supply of the DH driver.
9
DH
High-Side External MOSFET Gate-Driver Output. DH swings from BST to LX.
10
BST
Positive Supply of DH Driver. Connect a 0.1μF ceramic capacitor between BST and LX.
