该评估套件突出了?MC34716EP（1.0 MHz双通道开关模式DDR电源供应）， 它是高度集成、低成本，带集成N沟道功率MOSFET的双通道同步降压型开关稳压器。It is a high performance point-of-load (PoL) power supply with its second output having the ability to track an external reference voltage. it provides a full power supply solution for Double-Data-Rate (DDR) Memories.Channel one provides a source only 5.0?A drive capability, while channel two can sink and source up to 3.0?A. Both channels are highly efficient with tight output regulation. With its high current drive capability, channel one can be used to supply the VDDQ to the memory chipset. The second channel's ability to track a reference voltage makes it ideal to provide the termination voltage (VTT) for modern data buses. The MC34716 also provides a buffered output reference voltage (VREFOUT) to the memory chipset
