- Detailed Description-Power Management Functions
8.2.1 High voltage Current Sinks (DCDC_CURR1, DCDC_CURR2 and DCDC_CURR3)
Current sinks DCDC_CURR3, DCDC_CURR1 and DCDC_CURR2 can be controlled individually. The step-up DCDC
converter may supply them with voltages up to 15V. If any of these current sinks is used, connected VCURR_GPIO to
a supply with at least 3.0V .
