Freescale Semiconductor Advance Information Document number: MC34712 Rev. 4.0, 5/2007 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.
