Overview: Freescale Semiconductor, Inc. ANALOG PRODUCTS MC33702 FACT SHEET Freescale Semiconductor, Inc... 33702 MICROPROCESSOR POWER SUPPLY (3.0 A) The 33702 is a monolithic IC providing an efficient means of obtaining power for the Motorola Power QUICC I and II microprocessor families and other advanced microprocessors. The IC incorporates a high-performance synchronous switching regulator. The regulator is capable of delivering 3.0 A to power the microprocessor's core and linear circuitry to control an external low-drop FET for powering the microprocessor's I/O operations. Both regulator output voltages are independently adjustable. A boost converter allows high-accuracy output voltages to be developed from source operating voltages as low as 2.8 V. Seven ±1.0% Output Voltage Margining steps are provided to facilitate easy system development. APPLICATIONS POWER MANAGEMENT • Power Management of Advanced Microprocessor Based Systems • Telecom and Network Cards • Wireless Modems • ADSL Line Cards • Cable Modems • Li-ion Cell Equipment • Portable Equipment Simplified Application Diagram
