Technical Data
1.5A 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 high
performance 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, compact design.
The 34701 incorporates many advanced features; e.g., precisely
maintained up/down power sequencing, ensuring the proper
operation and protection of the CPU and power system.
