TPS25750: TPS25750 Sink Solution Schematic

Part Number: TPS25750
Other Parts Discussed in Thread: , USB-PD-CHG-EVM-01

Hello team,

I'm working on the full schematic of a power delivey sink solution. I've read that if the PD controller is used as a sink, it will be capable to feed the internals LDO and the digital core from the VBUS net.

Am I right? Because I want to save free space on the PCB but if I need any LDO to give 3v3 or 5v free space will be reduced..

If I don't have a 5V net what should I connect to PP5V?

If you have any schematic design as example it will be great!

Regards,

Nicolas

Hi Nicolas,

You can find a example schematic on page 55 of the datasheet as well as the TPS25750 schematic design on page 14 of the EVM User Guide (linked below). These schematic example should help clarify what is required. In addition, the EVM user Guide also includes a BOM for reference.

Regards,

Raymond Lin
