TPS548D22: RESV_TRK SS

Satoshi Yone

Part Number: TPS548D22
Other Parts Discussed in Thread: TPS548D21,

Hi, Team

For block diagram on datasheet page 12, there is an External soft-start inside the 37-pin RESV_TRK. Is it possible to adjust the SS even if an external C is added here?

Hi Satoshi,

This pin should be float for TPS548D22 (please see page 3 of datasheet). For further information of this pin, please see TPS548D21.

Hi Yone-san,

The RESV_TRK pin on the TPS548D22 is disabled internally so placing a C on this pin has no affect on the internal SS settings.

This is also described in the two threads below.
