Freescale Semiconductor Technical Data MC33701 Rev 4.0, 05/2005 1.5 A Switch-Mode Power Supply with Linear Regulator The 34701 provides the means to efficiently supply the Freescale Power QUICC™ 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 incorporates many advanced features; e.g.
