  • Publication number: 20240128867
    Abstract: A system includes: 1) a battery configured to provide an input voltage (VIN); 2) switching converter circuitry coupled to the battery, wherein the switching converter circuitry includes a power switch; 3) a load coupled to an output of the switching converter circuitry; and 4) a control circuit coupled to the power switch. The control circuit includes: 1) a switch driver circuit coupled to the power switch; 2) a summing comparator circuit configured to output a first control signal that indicates when to turn the power switch on; and 3) an analog on-time extension circuit configured to extend an on-time of the power switch by gating a second control signal with the first control signal, wherein the second control signal indicates when to turn the power switch off.

  • Patent number: 11920757
    Abstract: The present invention relates to a lamp for a vehicle and a vehicle. The lamp includes a housing and a light source arranged in the housing, an opening of the housing being divisible into one or more light emitting regions to correspondingly realize a predetermined light function, wherein the at least one light emitting region is provided with a light distribution element for the light source, the light distribution element having a first light distribution portion and a second light distribution portion, the first light distribution portion being configured to cause light of the light source to leave the light emitting region within a first angular range, and the second light distribution portion being configured to cause light of the light source to leave the light emitting region within a second angular range that is different from the first angular range.
