Hello everyone,
I've developed a new project with PSoC 5LP(The chip was used in CY8CKIT-50).
Now, I want to use a 3v battery supply to power the chip. I had read some datasheet, but I do not know how to do.
The working voltage of the chip is 1.71 - 5.5V.
So connect the battery and chip directly, or must boost to 3.3V / 5V?
Solved! Go to Solution.

For any custom board for supplying regulated Power from 1.8 V to 5.5V do the schematic as shown in page #3-4 of this AN-

In CY8CKIT-50, it can be supplied with 3.3 V / 5 V power supply on pins marked on connector P1.
You can try giving 3V at 3.3V marked pin.
Basically, the minimum voltage that can be applied to any VDDX power pin is 1.8 V.
