Freescale Semiconductor Advance Information Document Number: MC34716 Rev. 3.0, 5/2007 1.0 MHz Dual Switch-Mode DDR Power Supply The 34716 is a highly integrated, space-efficient, low cost, dual synchronous buck switching regulator with integrated N-channel power MOSFETs. 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 DoubleData-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.
