Boost Convertor
The PSoC 3 device has a unique capability of working from a voltage supply as low as 0.5 V. This is
possible using the boost convertor. The boost convertor uses an external inductor and a diode.
These components are pre-populated on the board.
To enable the boost convertor functionality, make the following hardware changes on the board.
■
■
After making these changes, you can make a boost convertor based design by making the
appropriate configurations in the project. The input power supply to the boost convertor must be
provided through the test points marked Vbat and GND.
Populate resistors R25, R27, R29, and R31
Ensure that R1 and R28 are not populated
