Patent number: 11677316Abstract: A variable duty cycle switching signal at a switching frequency is applied to a switching current regulation circuit arrangement energizing a current storage circuit assembly. Switching of the variable duty cycle switching signal is controlled by an upper and a lower threshold current level. The upper and lower threshold current levels vary with time following an average current value time variation. Additionally, frequency jitter is introduced in the variable duty cycle switching signal by: defining at least a frequency modulation window around a limit frequency identifying a limit value for an acceptable EMI; and applying an amplitude modulation of the upper and/or lower threshold current levels varying with time, wherein the amplitude modulation is applied in a time interval between times when the switching frequency enters and exit the frequency window.Type: GrantFiled: March 31, 2021Date of Patent: June 13, 2023Assignee: STMicroelectronics S.r.l.Inventors: Sebastiano Messina, Marco Torrisi
