A general-purpose evaluation platform that demonstrates the features of the AT73C224. The board is connected to the PC and is used with software to quickly evaluate the performance of its highly integrated 4-channel power supply (2 x DCDCs and 2 x LDOs in a small 5x5 mm QFN32 package). The kit includes an ultra-low power real-time clock (RTC) and backup battery management. The kit can be supplied by one single source, such as a single cell Li-Ion battery or any power supply between 3-5 volts.
