NAME
FUNCTION
FB
(MAX8570/
MAX8571/
MAX8574)
Feedback for setting the output voltage. Connect FB to the center of a resistor voltage-divider from the
output to GND to set positive output voltages.
1
OUT
(MAX8572/
MAX8573/
MAX8575)
Output. The output voltage is preset to 15V. Connect a 1μF ceramic capacitor from OUT to GND. In
shutdown, OUT is pulled to GND by an internal 7.5M
resistor.
2
GND
Ground
3
SHDN
Shutdown Input. A logic low at
SHDN
places the part in low-power shutdown mode. Pull
SHDN
high or
connect to V
CC
for normal operation.
Inductor Switching Connection
4
LX
5
SW
Isolation Switch Output. Internally connected to the drain of a p-channel MOSFET used to isolate the
output from the input during shutdown. Connect a 4.7μF ceramic capacitor from SW to GND. If true
shutdown is not required, SW can be left open with the input supply connected directly to the inductor.
6
V
CC
Input Voltage Supply. Connect a 2.7V to 5.5V input supply to V
CC
. Connect a 1μF ceramic capacitor from
V
CC
to GND.
