6. Si3460 Pin Descriptions
Si3460 pin functionality is described in Table 10. Note that the information applies to the Si3460 device pins, while
the Si3460-EVB User ’s Guide describes the inputs and outputs of the evaluation system.
The electrical characteristics of the Si3460-EVB are summarized in Table 1 on page 5. Refer to the complete
Si3460-EVB schematics and BOM listing for information about the external components needed for the complete
PSE and dc-dc controller application circuit.
