DCDC Initialization
Device Initialization

Description

Initialize the DC-DC converter.

Configures the DC-DC converter. If the DC-DC converter is not to be used, the configuration option SL_DEVICE_INIT_DCDC_ENABLE can be disabled, and the converter will be powered off. On Series 1 devices, this option should only be used when DVDD is externally powered.

To enable the bypass switch and short the DC-DC converter input to the DC-DC output, set the configuration option SL_DEVICE_INIT_DCDC_BYPASS .

See AN0948 Power Configurations and DC-DC for further details about DC-DC converter configuration and operation.
