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 capabi...
