He holds 2 patents that showcase his innovative approach to DC-DC converter systems. His work has significantly impacted the efficiency and functionality of power management solutions.

Latest Patents

One of Mathes' latest patents is for a "Synchronous buck converter with dynamically adjustable low side gate driver." This invention provides a DC-DC converter system that includes a high side switch and a low side switch coupled to a power supply. Each switch is designed to transition between on and off states to deliver current to an inductor and a load. The system features low side driver circuitry that controls the conduction state of the low side switch, utilizing two different gate driving signals for varying operational modes. The first gate driving voltage is stronger than the second, allowing for a slower switch transition when necessary.

Another significant patent is the "System and method to limit maximum duty cycle and/or provide a maximum volt-second clamp." This invention discloses a method to limit the maximum duty cycle of a pulse-width modulated (PWM) signal. Depending on the circuit topology, it can either limit the absolute duty cycle or function as a volt-second clamp. The duty cycle can be programmed by adjusting external reference components, ensuring high accuracy through component matching.
