Latest Patents

Wibowo's latest patents include a circuit and method of a switching converter with adaptive pulse insertion. This invention proposes a solution for a switching converter that modifies the clock frequency when the panic comparator is activated. The circuit is designed to increase the switching frequency in response to an undershoot condition, thereby minimizing voltage excursions. The switching converter circuit comprises at least one phase functional block configured to provide an output voltage, a panic comparator to evaluate voltage excursion conditions, and a clock generator with a pulse insertion function. This innovative approach aims to mitigate voltage excursions effectively.

Another significant patent by Wibowo is focused on phase-shifting optimization for asymmetric inductors in multi-phase DC-DC converters. This system minimizes peak-to-peak output voltage ripple in multi-phase DC-DC switching converters by optimizing phase-shifting determined by the inductance on each phase. The invention ensures both the AC accuracy of the output voltage and the efficiency of the DC-DC switching converter are enhanced. The improvements in output voltage ripple are shown to be dependent on the duty cycle, while also minimizing total inductor current ripple and reducing capacitor loss.
