PIN DESCRIPTION
PIN NUMBER
PIN NAME
DESCRIPTION
1
PV
IN
Input voltage power pin. Inductor charging current passes
through this pin.
2
V
IN
Internal supply voltage. Control circuitry powered from this
pin.
3
BLON
Open drain battery low output. V
below battery low thresh-
old pulls this node to ground. V
IN
above threshold, this node
is open.
4
I
LIM
Inductor current limit programming pin. Tie pin to V
for 0.8A
peak inductor current limit. Tie pin to ground for 0.4A peak
inductor current limit. TTL input threshold.
5
SHDN
Shutdown control input. Tie to V
for normal operation, tie to
ground for shutdown. TTL input threshold.
6
FB
External feedback network input connection. Connect a
resistor from FB to ground and FB to V
to control the
output voltage externally. This pin regulates to the internal
bandgap reference voltage of 1.25V. Tie FB to ground to use
the internal divider for a preset output voltage of 3.3V.
7
V
OUT
Output voltage sense pin. Used for internal feedback divider
and timing circuit.
8
GND
Internal ground pin. Control circuitry returns current to this
pin.
9
PGND
Power ground pin. Synchronous rectifier current returns
through this pin.
10
LX
Inductor switching node. Inductor tied between this pin and
the output capacitor to create regulated output voltage.
