NAME
FUNCTION

B3
Open-Drain Output PNP Transistor Driver (Regulator 3). Internally connected to the
drain of a DMOS. B3 connects to the base of an external PNP pass transistor to form a
positive linear regulator.

FB3
Analog Gain Block Feedback Input (Regulator 3). Connect to a resistive-divider
between the positive linear regulator
’
s output and GND to adjust the output voltage.
The feedback set point is 1.24V.

B4
Open-Drain Output PNP Transistor Driver (Regulator 4). Internally connected to the
drain of a DMOS. B4 connects to the base of an external PNP pass transistor to form a
positive linear regulator.

B5
Open-Drain Output NPN Transistor Driver (Regulator 5). Internally connected to the
drain of a P-channel MOSFET. B5 connects to the base of an external NPN pass
transistor to form a negative linear regulator.

12
FB5
Analog Gain Block Feedback Input (Regulator 5). Connect to a resistive-divider
between the negative linear regulator
’
s output and a positive reference voltage,
typically one of the positive linear regulator outputs, to adjust the output voltage. The
feedback set point is at GND.

ILIM
Dual-Mode Current-Limit Adjustment Input. Connect to VL for the default 250mV
current-limit threshold. In adjustable mode, the current-limit threshold voltage is 1/5 th
the voltage present at ILIM. Connect to a resistive-divider between VL and GND to
adjust V
ILIM
between 500mV and 2.5V. The logic threshold for switchover to the 250mV
default value is approximately VL - 1V.
Ground
Low-Side Gate-Driver Output. DL swings between GND and VL.

LX
Inductor Connection. Used for current-sense between IN and LX, and used for current-
limit between LX and GND.
13
17
DH
High-Side Gate-Driver Output. DH swings between LX and BST.
14
18
BST
Boost Flying Capacitor Connection. Connect BST to the external boost diode and
capacitor as shown in the
Standard Application Circuit
.
15
19
VL
Internal 5V Linear Regulator Output. Supplies the IC and powers the DL low-side gate
driver and external boost diode and capacitor. Bypass with a 1
μ
F or greater ceramic
capacitor to GND.
16
20
IN
Input Supply Voltage. 4.5V to 28V. Bypass to GND with a 1
μ
F or greater ceramic
capacitor close to the IC.
