VREF
5.1V Reference voltage with 20mA current capability.

OSC
An external resistor connected between the unregulated
input voltage and this pin and a capacitor connected
from this pin to ground fix the switching frequency. (Line
feed forward is automatically obtained)

OUT
Stepdown regulator output.

VCC
Unregulated DC input voltage.

BOOT
A capacitor connected between this pin and OUT allows
to drive the internal VDMOS.
7

COMP
E/A output to be used for frequency compensation.

FB
Stepdown feedback input. Connecting directly to this pin
results in an output voltage of 3.3V. An external resistive
divider is required for higher output voltages.
