  • Patent number: 10992229
    Abstract: An electrical system includes: 1) a buck converter; 2) a battery coupled to an input of the buck converter; and 3) a load coupled to an output of the buck converter. The buck converter includes a high-side switch, a low-side switch, and regulation loop circuitry coupled to the high-side switch and the low-side switch. The regulation loop circuitry includes a comparator with preamplifier gain adjustment circuitry configured to adjust a preamplifier gain of the comparator based on an overdrive voltage.

    Abstract: An electrical system includes: 1) a buck converter; 2) a battery coupled to an input of the buck converter; and 3) a load coupled to an output of the buck converter. The buck converter includes a high-side switch, a low-side switch, and regulation loop circuitry coupled to the high-side switch and the low-side switch. The regulation loop circuitry includes: 1) a main comparator; 2) a bias current source coupled to the main comparator and configured to provide a bias current to the main comparator; and 3) a dynamic biasing circuit coupled to the main comparator and configured to add a supplemental bias current to the bias current in 100% mode of the buck converter. The supplemental bias current varies depending on an input voltage (VIN) and an output voltage (VOUT) of the buck converter.

  • Publication number: 20200106360
    Abstract: A switching converter circuit includes a voltage regulation loop configured to provide an output voltage (VOUT) based on an input voltage (VIN). The switching converter circuit also includes a 100% mode circuitry coupled to the voltage regulation loop, wherein the 100% mode circuitry is configured to apply an offset to VOUT in response to detecting that VIN is approaching VOUT.
