PIN FUNCTIONS
VFB200B (Pin 1): 200mA Regulator B Feedback Pin. This
pin receives the feedback voltage from an external resistive
divider across the output.
VFB200A (Pin 2): 200mA Regulator A Feedback Pin. This
pin receives the feedback voltage from an external resistive
divider across the output.
RUN200A (Pin 3): 200mA Regulator A Enable Pin. Forcing
this pin to VIN enables the 200mA regulator (channel A),
while forcing it to GND causes the regulator to shut off.
SW200B (Pin 4): Switch Node Connection to Inductor for
200mA Regulator B. This pin connects to the drains of the
internal power MOSFET switches.
SW200A (Pin 5): Switch Node Connection to Inductor for
200mA Regulator A. This pin connects to the drains of the
internal power MOSFET switches.
PGND (Pin 6): Power Path Return Pin for Both 200mA
Regulators and the 300mA Regulator.
PVIN (Pin 7): Power Path Supply Pin for Both 200mA
Regulators and the 300mA Regulator. This pin must
be closely decoupled to PGND, with a 4.7μF or greater
ceramic capacitor.
SW300 (Pin 8): Switch Node Connection to Inductor for
300mA Regulator. This pin connects to the drains of the
internal power MOSFET switches.
RUN300 (Pin 9): 300mA Regulator Enable Pin. Forcing
this pin to VIN enables the 300mA regulator, while forcing
it to GND causes the regulator to shut off.
VFB300 (Pin 10): 300mA Regulator Feedback Pin. This pin
receives the feedback voltage from an external resistive
divider across the output.
VFB100 (Pin 11): 100mA Regulator Feedback Pin. This pin
receives the feedback voltage from an external resistive
divider across the output.
RUN100 (Pin 12): 100mA Regulator Enable Pin. Forcing
this pin to VIN enables the 100mA regulator, while forcing
it to GND causes the 100mA regulator to shut off.
SW100 (Pin 13): Switch Node Connection to Inductor for
100mA Regulator. This pin connects to the drains of the
internal power MOSFET switches.
GNDA (Pin 14): Ground Pin for Internal Reference and Con-
trol Circuitry. Power path return for the 100mA regulator.
VCC (Pin 15): Supply Pin for Internal Reference and Control
Circuitry. Power path supply pin for the 100mA regulator.
RUN200B (Pin 16): 200mA Regulator B Enable Pin. Forcing
this pin to VIN enables the 200mA regulator (channel B),
while forcing it to GND causes the regulator to shut off.
Exposed Pad (Pin 17): Ground. Must be soldered to PCB.
