Power supply system
The power supply system on this board is versatile, allowing the input supply to come from the following sources:
•
5 V, 9 V, or 12 V from the on-board USB Type-C connector
•
5 V to 12 V power from a shield compatible with Arduino or from external power supply through VIN header J9
or J1
•
3.7 V from a rechargeable Li-Po battery connected to J15
•
5 V from an external programmer/debugger connected to J11 and J12
The power supply system is designed to support 1.8 V to 3.3 V operation of the PSoC™ 6 MCU. In addition, an
intermediate voltage of 5 V is required for operation of the KitProg3. Therefore, three regulators are used to
achieve 1.8 V to 3.3 V and 5 V outputs – a buck boost regulator (U30) that generates a fixed 5 V from an input of 5
V to 12 V, and a main regulator (U10) that generates either a variable 1.8 V to 3.3 V, or a fixed 1.8 V, or a fixed 3.3 V
from the output of U30.
The voltage selection is made through switch SW5. For details of the PSoC™ 6 MCU backup system and power
supply, see the
PSoC™ 62 architecture reference
Note:
Starting with Rev. *F of the kit, the super capacitor is removed. Therefore, you must keep SW7 at
VDDD/KITPROG3 position. If not, the kit will be unpowered, and you will notice flickering on the TFT
display.
