Pin Description
PIN
NAME
FUNCTION
1
BATT
Inductor Supply Voltage, 0.8V to 5.5V. Internally connected to the source of a P-channel
MOSFET used to isolate the output from the input during shutdown. Bypass with a 10
μ
F or
greater capacitor.
2
FB
Feedback Input. Connect to a resistive divider network between the output and GND to set the
output voltage between V
BATT
and 28V. The feedback threshold is 1.25V.
IC Supply Voltage, 2.4V to 5.5V. Bypass V
CC
to GND with a 1
μ
F or greater capacitor.

Ground
5
LX
Inductor Switching Connection. Internally connected to the drain of a 28V N-channel MOSFET.
LX is high impedance in shutdown.
6
LIM
Inductor Current-Limit Selection. Connect LIM to V
CC
for 500mA, leave LIM floating for 250mA,
or connect LIM to GND for 125mA.
7
SHDN
Active-Low Shutdown Input. A logic low shuts down the device and reduces the supply current
to 0.1
μ
A. When shutdown, the MAX1606 isolates the output from the input by turning off the P-
channel MOSFET between BATT and SW. Connect
SHDN
to V
CC
for normal operation.
8
SW
Isolation Switch Output, Inductor Connection. Internally connected to the drain of a P-channel
MOSFET used to isolate the output from the input during shutdown.
