Ultralow Noise, High Current, Compact DC-to-DC Converter Solution for Signal and Data Processing Circuits
White Paper Overview
Data processing ICs—such as field-programmable gate arrays (FPGAs), systems on a chip (SoCs), and microprocessors—continually increase their reach into telecommunications, networking, industrial, automotive, avionics, and defense systems. One common thread throughout these systems is ever-increasing processing power, resulting in corresponding increases in raw power requirements. Designers are well aware of the thermal management problems of high-power processors but may not consider the thermal management issues of power supplies. Not unlike the transistor-packed processors themselves, worst-case thermal problems are inevitable when low core voltages require high current—the overall trend for the power supplies for all data processing systems.
This white paper covers the following:
- Conversion Ratio, Size, and Thermal Considerations
- Reducing Size While Improving EMI and Thermal Performance, and Efficiency
- Monolithic Radiators
- Differential Voltage Sensing for High Current Loads
- Monitoring Output Current
- Parallel Operation for Higher Currents and Better Thermal Performance
