Digital power conversion is a power system that is controlled by digital circuits, in much the same way as would be with analog circuits, to monitor, supervise, communicate and control looping. A fully digitally controlled power system includes both digital control and digital power management. Control loops provide the mechanism by which to regulate the output of the power supply, usually through pulse width modulation of a power switch. Power management techniques provide the ability to monitor temperature, provide overcurrent protection, and supply sequencing.
Freescale digital signal controllers are the right solution for digital power conversion applications. Freescale's DSCs provide both the control loop and power management functionality on one platform. By providing outstanding digital signal processing capabilities, high–speed PWMs, and extremely accurate ADCs, Freescale DSCs maximize system performance and reliability.
