DESCRIPTION
1
COMP
Compensation pin. Output of the internal error amplifier. Capacitor and resistor from COMP pin to ground.
2
FB
Voltage feedback pin. Internal reference is 1.294V nominal. Connect a resistor divider from VOUT. VOUT =
1.294V (1 + R1 / R2). See Typical Application Circuit.
3
SHDN
Shutdown control pin. Pull SHDN low to turn off the device.
4
GND
Analog and power ground.
5
LX
Power switch pin. Connected to the drain of the internal power MOSFET.
6
VDD
Analog power supply input pin.
7
FSEL
Frequency select pin. When FSEL is set low, switching frequency is set to 620kHz. When connected to
high or VDD, switching frequency is set to 1.25MHz.
8
SS
Soft-start control pin. Connect a capacitor to control the converter start-up.
