Introduction

Mark Robert Vitunic is an accomplished inventor based in Lexington, MA. With a remarkable portfolio of seven patents, he has contributed significantly to the field of electrical engineering, particularly in the realm of DC-DC converters and voltage regulation.

Latest Patents

Among his most recent innovations are two notable patents focused on improving the performance of inductor-based DC-DC converters. The first patent details techniques for linear control of inductor current shunt aimed at mitigating load dump transients in DC-DC regulators. This innovative design incorporates a current shunt switch that provides an alternate pathway for inductor current, excluding the output capacitor. An amplifier circuit is integrated with a control node of the current shunt switch to finely adjust the voltage, regulating the amount of inductor current redirected away from the output node. This approach is essential for ensuring smooth transitions during the engagement or disengagement of the current shunt switch, minimizing negative output voltage excursions during transient conditions.

The second patent improves voltage regulation further by introducing a shunt circuit that operates in parallel with the inductor. This shunt circuit effectively diverts inductor current when the output voltage surpasses a predefined maximum value, allowing for more stable output performance, particularly during load transients.
