dcdc_framework
Overview
This demo is used to show a kind of usage of DCDC function. In this case, the DCDC is used as the voltage regulator instead of on-chip LDOs. For the condition that DCDC input voltage is not so stable, as the battery’s voltage decrease after a few working time, a timer is used to trigger the adjustment by sampling the ADC value of bandgap/battery input voltage, calculating them and setting the result into the DCDC module, so that the output of DCDC would be adjusted and kepted constant as much as possible. Actually, this use case is usually used in the connectivity application, and the period of adjust (configured by the timer’s timeout period) is also setup according to requirement.
