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 providing 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, compact design.
The 34701 incorporate...
