Pin Descriptions
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. This pin has an internal pulldown resistor so the
default condition is off. The pin must be pulled high to turn on the device.
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 = 1.25MHz. Ground = 615kHz.
8
SS
Soft-start Pin.
