MCZ34701EW

专业电源管理 PMIC 1.5A Sw-Mode Power Supply w/Linear Reg

The 34701 provides the means to efficiently supply the Freesca Power QUICC™ I, II, and other families of 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.
