MC34712EP/R2规格书详情
3.0 A 1.0 MHz Fully Integrated DDR Switch-Mode Power Supply
The 34712 is a highly integrated, space efficient, low cost, single synchronous buck switching regulator with integrated N-channel power MOSFETs. It is a high performance point-of-load (PoL) power supply with the ability to track an external reference voltage.
Its high efficient 3.0 A sink and source capability combined with its voltage tracking/sequencing ability and tight output regulation, makes it ideal to provide the termination voltage (VTT) for modern data buses such as Double-Data-Rate (DDR) memory buses. It also provides a buffered output reference voltage (VREF) to the memory chipset
The 34712 offers the designer the flexibility of many control, supervisory, and protection functions to allow for easy implementation of complex designs. It is housed in a Pb-free, thermally enhanced, and space efficient 24 Pin Exposed Pad QFN.
