The key to high efficiency is well managed power management.
Power management can be done efficiently with integrated on-chip solutions. Higher power levels might however call for external switching devices. In both cases an ASIC can measure, control, and supervise the power conversion in an optimized way. Incorporating this functionality helps reducing PCB footprint.
Examples of power control application areas:
|Switched drivers||Motor control|
|Supervision of external power devices||Linear regulators|
|Relay control||DC/DC converters|
