Notes
1. ESD1 testing is performed in accordance with the Human Body Model (CZAP=100 pF, RZAP=1500 ), ESD2 testing is performed in
   accordance with the Machine Model (CZAP=200 pF, RZAP=0 ), and the Charge Device Model.
2. Lead soldering temperature limit is for 10 seconds maximum duration.
3. Junction temperature is a function of on-chip power dissipation, package thermal resistance, mounting site (board) temperature,
   ambient temperature, air flow, power dissipation of other components on the board and board thermal resistance.
4. Per JEDEC JESD51-6 with the board horizontal
5. Thermal resistance between the die and the printed circuit board per JEDEC JESD51-8. Board temperature is measured on the top
   surface of the board near the package.

Description

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 of 34701 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.
