3.2.3 Measuring Power Consumed by HX3PD Controller
HX3PD is powered by 1.2 V and 3.3 V power domains. The total power consumed by HX3PD can be measured using the following
procedure any time during the operation of the kit. Note that this procedure requires two digital multimeters to measure current
consumed on 1.2 V and 3.3 V domains simultaneously.
1. Detach the power supply from the CY6611 EVK board.
2. Remove the jumpers installed at jumper headers J6 (1.2-V supply) and J10 (3.3-V supply).
3. Set both the digital multimeters in Ampere mode and attach them to headers J6 and J10.
4. Supply power to the CY6611 EVK board and operate the features of the kit as required. See the
more details.
5. Measure the current consumed on both 1.2 V (J6) and 3.3 V (J10) domains
6. The total power consumed by HX3PD can be calculated as:
HX3PD Power Consumption (mW) =
1.2 x (measured current in 1.2V domain) + 3.3 x (measured
current in 3.3 V domain)
