5 A Switch-Mode Power Supply with Linear
Regulator
The 34701 provides the means to efficiently supply the Freescale Power QUICCâ„¢ I, II, and other families of Freescale microprocessors and DSPs.
The 34701 incorporates a highperformance switching
regulator, providing the direct supply for the microprocessor’s core, and a low dropout (LDO) linear
regulator control circuit provides the microprocessor I/O and bus voltage.
The switching
regulator is a high-efficiency synchronous buck
regulator with integrated N-channel power MOSFETs to provide protection features and to allow space-efficient, c...
