Who
- Daniel Puratich Architecture & Management
- Kenny Na EE Designer, Documentation
What
- A USB-C PD sink where the output voltage can be selected with resistors
  - DNP and fitted resistors
- Intent for requesting 20V 65W when debugging https://uwarg-docs.atlassian.net/wiki/spaces/EL/pages/2701197313/RPi+Interface+Rev+C?atl_f=content-tree setup without the full drone, but should support 12V and 5V as well for testing other boards
- Use a USB-C PD chip and the associated required FETs that are required for negotiation
- Ideally does not require a microcontroller, due to cost constraints
- USB-C input connector / XT30 output connector
- don't worry about board area too much but it can be tiny
- no buck converterto XT30 adapter to deliver up to 100W (20V 5A) to a drone during stationary testing.
  - Configuration identifiable on the board via circled value on backside silkscreen.
- PD arbitration handled by the TPS25730; power configuration with resistor dividers on ADC pins.
- Excludes the use of a microcontroller or dedicated buck/boost converters to save on BOM cost.
