Power modes
EZ-PD
™
PMG1 MCU kits support two types of powering modes: programming mode and operational mode.
The power selection jumper position decides the power input connected to the MCU and selects between the
programming and operation power supply. Short pins 1
–
2 for operational mode (VBUS Type-C) and short 2
–
3
for programming mode (VIN).

3.2.1.1
Programming mode
For programming using the onboard KitProg3, the kit gets powered through the KitProg3 USB Type-C port (J1).
When the programming mode setting is selected, power from the programming connector gets connected to
the VBUS pin of the EZ-
PD™
PMG1 MCU.
3.2.1.2
Operational mode
For normal operation, the prototyping kit gets powered through the EZ-
PD™
PMG1 USB PD sink port. This
voltage is directly connected to the VBUS pin via the power selection jumper, and the internal LDO down
converts VBUS voltage to 3.3 V for chip operation.
The CY7110, CY7111, and CY7112 kits support USB PD contracts up to 100 W (20 V, 5 A). The CY7113 kit supports
USB PD contracts up to 140 W (28 V, 5 A).
