To power the DC2369A demo circuit, you need to set the slide switch SW1 to the ON position. The circuit is powered by two AAA batteries, which are included with the demo circuit. The slide switch asserts the enable pin of the LTC3335 power supply. To verify the correct operation of the power supplies, you can measure the voltage between VDD and GND on the back of the circuit board, which should be 3.3V, and the voltage between VREF and GND, which should be 3.0V. Please refer to the DC2369A instruction manual for more information on powering the circuit.
