Frequently Asked Questions

What types of DC-DC converters does Will Semiconductor offer?

Will Semiconductor offers a comprehensive range of DC-DC converters including synchronous buck converters for step-down voltage regulation

boost converters for step-up applications

and buck-boost converters for applications where input voltage can be above or below the output. These converters support input voltages from 2.5V to 60V and output currents up to 10A. Features include high switching frequencies (up to 3MHz) for compact designs, programmable soft-start, and comprehensive protection features. The portfolio includes both integrated solutions with internal power switches and controllers for external FET configurations.

Select converter type based on your input/output voltage relationship and current requirements. Contact us for power architecture recommendations.

How do I choose between switching regulators and LDOs?

The choice between switching regulators (DC-DC) and LDOs depends on your application requirements. Switching regulators offer higher efficiency (typically 85-95%) and can step up or step down voltage, but generate more noise and require external inductors. LDOs provide clean output with very low noise and no switching ripple, but are less efficient when input voltage is much higher than output. Use switching regulators for high current applications or when efficiency is critical. Use LDOs for noise-sensitive analog circuits or when input-output voltage difference is small. Will Semiconductor offers both types with various performance characteristics.

For noise-sensitive applications, consider LDOs. For battery-powered devices, switching regulators are preferred. Contact us for power architecture guidance.

Select LED driver based on your LED configuration, current requirements, and dimming method. Contact us for LED driver recommendations.

What is the efficiency of Will Semiconductor DC-DC converters?

Will Semiconductor DC-DC converters achieve high efficiency through synchronous rectification and advanced control algorithms. Typical efficiency ranges from 85% to 95% depending on input/output voltage ratio and load current. Peak efficiency is usually achieved at 50-80% of rated load. Light-load efficiency is optimized through PFM (Pulse Frequency Modulation) or burst mode operation. The efficiency curves are characterized across the full operating range and are available in datasheets. For battery-powered applications, high efficiency directly translates to longer battery life.
