The 34702 provides the means to efficiently supply the Freescale Power QUICCTM I, II, and other families of Freescale microprocessors and DSPs. The 34702 incorporates a high performance 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 34702 incorporates many advanced features; e.g., precisely maintained up/down power sequencing, ensuring the proper operation and protection of the CPU and power system.
