ALEXANDRIA, Va., Sept. 30 -- United States Patent no. 12,431,805, issued on Sept. 30, was assigned to Robert Bosch GmbH (Stuttgart, Germany).

"Buck-boost based high linearity driver with separately controllable duty cycle for energizing and de-energizing phases" was invented by Chau Nguyen (Santa Clara, Calif.) and Chinwuba Ezekwe (Albany, Calif.).

According to the abstract* released by the U.S. Patent & Trademark Office: "A variable de-energizing phase duty cycle Dd is generated based on an input signal to optimize for a low duty cycle in a freewheeling phase. A variable energizing phase duty cycle De is generated based on a buck-boost control loop tracking the input signal. A tri-state buck-boost converter is controlled using the variab...
