NAME
FUNCTION
1
IN
Supply Voltage Input. Input range from +2.7V to +5.5V. Bypass with a 2.2
μ
F ceramic capacitor to
GND.
2
GND
Ground
3
SHDN
Active-Low Shutdown Input. Connect
SHDN
to IN for normal operation. In shutdown, LX becomes
high impedance and quiescent current drops to 0.01
μ
A.
FB
MAX1733 Voltage Feedback Input. FB regulates to 1.25V nominal. Connect FB to an external
voltage-divider between the output voltage and GND.
4
OUT
MAX1734 Voltage Sense Input. OUT is connected to an internal voltage-divider.
5
LX
Inductor Connection
