Overview

The MCUXpresso SDK provides APIs for MCUXpresso SDK devices' dcdc operation.

The DCDC Converter(DCDC) is used for generating the power supply for the chip's core logic. It can provide two outputs for SoC peripherals and external devices with high conversion efficiency. As a module to provide the power for hardware system, the DCDC starts working when the system is powered up before the software takes over the SoC. Some important configuration is done by the board settings. Before the software can access the DCDC's register, the DCDC is already working normally with the default settings. However, if the application needs to improve the DCDC's performance or change the default settings, this DCDC driver would be helpful. The DCDC's register cannot be accessed by software before its initialization (open the clock gate).

The DCDC module supports two control modes: Static control mode and Set point control mode. When the module controlled by GPC set points, that is set point control mode, the DCDC_SetPointInit() function can be used to enable DCDC module, set outputs' target voltage in the specific set point. When the control mode is set as static control mode, to change the target voltage value of DCDC's outputs, the APIs in "Outputs' Target Voltage Related Interfaces" function group can be used. To set DCDC module's power mode, the APIs in "Power Mode Related Interfaces" function group can be used.
