  • BOOT UVLO detection scheme for high voltage applications
    Patent number: 12620889
    Abstract: A buck converter including a high-side switch, a low-side switch and a bootstrap (BOOT), under-voltage lockout (UVLO) circuit. The BOOT UVLO circuit includes a BOOT UVLO detection element configured to compare a BOOT voltage with a switch node (SW) voltage to determine an occurrence of a BOOT UVLO event. The BOOT UVLO detection element is configured to output an UVLO signal (UVLO_Z), in case of the BOOT UVLO event. The BOOT UVLO circuit further includes a logic gate configured to receive the UVLO_Z and a high-side ON, (HSON) signal, the HSON signal is for controlling a switching of the high-side switch. The logic gate is configured to negate the HSON signal when receiving the UVLO_Z while the HSON signal is ON, to thereby immediately switch OFF the high-side switch when the HSON signal is ON.

  • SWITCHED MODE POWER SUPPLY ARRANGED FOR EFFICIENTLY POWERING A RANGE OF LOADS AND METHOD OF OPERATING SUCH
    Publication number: 20260121506
    Abstract: A Switched Mode Power Supply (SMPS) with a switching stage has a high-side switch, a low-side switch, and an output inductor. The SMPS also has control circuitry for controlling the high-side switch and the low-side switch based on a clock signal. The control circuitry is configured to detect that an output voltage of the switching stage deviates from a reference voltage and thereby enable negative valley regulation. Upon enabling negative valley regulation, the control circuitry detects that a current flowing through the inductor falls below a threshold and, based on the detection, initiates a next clock cycle of the clock signal.
