FUNCTION
No Connect. These pins are internally connected to the common switch
node of the internal MOSFETs. NC(SW) pins are not to be electrically
connected to any external signal, ground, or voltage. However, they
must be soldered to the PCB. Failure to follow this guideline may result
in part malfunction or damage.
Power Ground.
Feed back pin for external divider option. When using the external
divider option (VS2=VS1=VS0= high) connect this pin to the center of
the external divider. Set the divider such that VFB = 0.603V. The
“ground” side of the external divider should be connected to AGND.
Sense pin for preset output voltages. Connect at the output capacitor.
Analog ground. This is the quiet ground for the internal control circuitry
Regulated Output Voltage. Refer to application section for proper layout
and decoupling.
No Connect. This pin should not be electrically connected to any
external signal, voltage, or ground.. This pin must be soldered to the
PCB.
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. (refer to section on output voltage select for
more detail).
Output enable. Enable = logic high, disable = logic low.
Input voltage pin.
