NO CONNECT – These pins should not be electrically connected to each other or to any
external signal, voltage, or ground. One or more of these pins may be connected internally.
These pins must be soldered to the PCB.
Power Ground
Feed back pin for external divider option. When using the external divider option
(VS0=VS1=VS2= high) connect this pin to the center of the external divider. Set the divider
such that VFB = 0.6V. The “ground” side of the external divider should be connected to
AGND.
Sense pin for preset output voltages. Connect this to V
to ensure the best regulation.
Analog ground. This is the quiet ground for the internal control circuitry.
Regulated Output Voltage
Output voltage select. VS2=pin10 VS1=pin11, VS0=pin12. Selects one of seven preset
output voltages or choose external divider by connecting pins to logic high or low. Logic low
is defined as V
two values is indeterminate. (Refer to section on output voltage select for more detail).
Output enable: Enable = logic high, disable = logic low. Logic low is defined as V
Logic high is defined as V
Input voltage pin. Supplies power to the IC.
