In summary, the ADP2102 can be a key component to extending battery life in mobile applications that include a DSP. The ADP2102 can be configured as an external voltage regulator which will reduce the DSP’s core voltage when it does not require the additional power to perform more intensive tasks. Also, for the Blackfin DSP used as the example in this module, using the ADP2102 requires less board space than configuring the Blackfin to use its internal voltage controller.
