  • Publication number: 20220416666
    Abstract: A first comparator is enabled during a period in which a wake-up signal is asserted and asserts a first detection signal indicative of a comparison result between a first feedback voltage generated by a first voltage dividing circuit and a first threshold voltage. A second comparator is always enabled and asserts a second detection signal indicative of a comparison result between a second feedback voltage VFB generated by a second voltage dividing circuit and a second threshold voltage VTH. A logic circuit generates a first pulse signal based on a first detection signal or a second detection signal, asserts the wake-up signal in a non-light load state, and negates the wake-up signal in a light load state.

  • Publication number: 20220407421
    Abstract: A main comparator compares a feedback voltage VFB corresponding to an output voltage VOUT of a DC/DC converter with a reference voltage VREF and asserts a turn-on signal when the feedback voltage VFB falls below the reference voltage VREF. A timer circuit generates a turn-off signal S2 that transitions in level after an ON time TON proportional to (VOUT?VIN/VOUT has elapsed from assertion of the turn-on signal.

  • Patent number: 11385176
    Abstract: In a cover device for a near-infrared sensor, a plate-shaped cover is arranged in a vehicle such that near-infrared light transmitted from a near-infrared sensor passes through the cover in the thickness direction. A part of the cover in the thickness direction is constituted by a bright decorative layer, which reflects part of incident visible light and allows near-infrared light to pass through. The cover is configured such that the near-infrared light transmittance is higher than the visible light transmittance. The vehicle further includes a light emitting portion, which emits visible light to the cover.
