Preliminary Information 3.
0 A Switch-Mode Power Supply with Linear
Regulator
The 33702 provides the means to efficiently supply the Power QUICC™ I, II, and other families of Motorola microprocessors and DSPs.
The 33702 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 50 mΩ N-channel power MOSFETs to prov...
