Specification

USB-C Trigger for fixed PDOs, or PPS with Constant Voltage or Constant Current mode. The operating trigger range is 3.3V-21V @ 3A max.

How to use the board

• Default (no jumper): CV mode. Max voltage is set by the potentiometer. Maximum current rated for cable/power supply.
• 1A jumper: CC mode at 1A. Max voltage is set by the potentiometer.
• 1.5A jumper: CC mode at 1.5A. Max voltage is set by the potentiometer.
• 2A jumper: CC mode at 2A. Max voltage is set by the potentiometer.
• 2.5A jumper: CC mode at 2.5A. Max voltage is set by the potentiometer.
• 3A jumper: CC mode at 3A. Max voltage is set by the potentiometer.
• 4A jumper: No application

When CC mode is selected through the jumper, if the power supply does not support PPS mode, there will be no power at the output. This is a sanity check for CC mode.

*CC: Constant Current Mode *CV: Constant Voltage Mode

Important note

Not all USB-C power supplies support Programmable Power Supply (PPS). and not all PPS power supplies support CC mode. Through our small sample size that includes powerbank/charger from Anker, Ugreen, and Baseus, here is our recommendation for getting Constant Current mode out of the box:

• UGREEN 100W USB PD 3.0
• UGREEN 140W USB PD 3.1
• UGREEN 160W USB PD 3.1
• Anker 737 GaNPrime 120W
• Anker 737 PowerCore 24K

Our lab recommends using the UGREEN Nexode charger. There is another Ugreen Nexode charger that our lab has not tested. Your feedback on that charger will be appreciated!

We recommend using CC mode whenever possible as it will limit the output voltage to 3A or less using PPS. Standard profiles do not have a current limit and can result in pushing more than 3A over a 3A-rated cable if the source is not 100% compliant. In CC mode, only the PPS profile is activated, if there is no PPS profile, the output is turned off.

In Constant Voltage, the trigger board will try to utilize the PPS profile if it exists before using the standard fixed profile to provide the requested voltage from the potentiometer..
