PINTYPEDESCRIPTION
NAMENO.
GNDD2PWRGND supply pin. Connect this pin close to the GND terminal of the input and output capacitor.
VOSD1INOutput voltage sense pin for the internal feedback divider network and regulation loop. This pin also discharges VOUT by an internal MOSFET when the converter is disabled. Connect this pin directly to the output capacitor with a short trace.
VINC2PWRVIN power supply pin. Connect the input capacitor close to this pin for best noise and voltage spike suppression. A ceramic capacitor is required.
SWC1PWRThe switch pin is connected to the internal MOSFET switches. Connect the inductor to this terminal.
VSELB2IN

Voltage Selection Pin. Can be toggled during operation. LOW = 0.6 V(TPS628600/10), 1.05 V(TPS628603), HIGH = 1.1 V(TPS628600/10), 0.65 V(TPS628603)

ENB1INA high level enables the devices and a low level turns the device off. The pin features an internal pulldown resistor, which is disabled after the device has started up.
SDAA2INI2C serial data pin. Do not leave floating.
SCLA1INI2C serial clock pin. Do not leave floating.
