Pin Description
Pin
Name
Function
1V
C
Compensation network connection. Connected to the output of the voltage error amplifier.
2
FB
Output voltage feedback input.
3
SHDN
Shutdown control input, active low.
4
GND
Analog and power ground.
5
SW
Power switch input. Switch connected between SW pin and GND pin.
6V
IN
Analog power input.
7
FSLCT
Switching frequency select input. V
IN = 1.3MHz. Ground = 600kHz.
8
NC
Connect to ground or leave open. Connect to GND pin directly beneath the device if
possible. If other traces are in the way or it is otherwise not possible to directly connect it
to GND leave this pin open and shield it from sources of EMI.
