DESCRIPTION
NAME
NO.
SYNC_OUT
14
O
Internal clock output pin for synchronization in stacked mode. Leave this pin floating for single
device operation. Connect this pin to the MODE/SYNC pin of the next device in the daisy-chain in
stacked operation. Do not use this pin to connect to a non-TPS6287x device.
During start-up, this pin is used to identify if a device must operate as a secondary converter in
stacked operation. Connect a 47kΩ resistor from this pin to GND to define a secondary converter
in stacked operation. See Section 7.3.17 for a detailed description.
VSEL
15
—
Start-up output voltage select pin. A resistor or short circuit to GND or VIN defines the selected
output voltage. See Section 7.3.6.2.
FSEL
16
—
Frequency select pin. A resistor or a short circuit to GND or VIN determines the free-running
switching frequency. See Section 7.3.6.2.
Exposed Thermal Pad
—
The thermal pad must be soldered to GND to achieve an appropriate thermal resistance and for
mechanical stability.
