Abstract: A hybrid power conversion circuit includes a high-side switch, a low-side switch, a transformer, a resonance tank, a first switch, a second switch, a first synchronous rectification switch, a second synchronous rectification switch, and a third switch. The resonance tank has an external inductor, an external capacitance, and an internal inductor. The first switch is connected to the external inductor. The second switch and a first capacitance form a series-connected path, and is connected to the external capacitance. The first and second synchronous rectification switches are respectively coupled to a first winding and a second winding. The third switch is connected to the second synchronous rectification switch. When an output voltage is less than a voltage interval, the hybrid power conversion circuit operates in a hybrid flyback conversion mode, and otherwise the hybrid power conversion circuit operates in a resonance conversion mode.

Abstract: A cooling system for a heat-generating electronic device includes a cold plate module, a flow channel, and a fin arrangement. The cold plate module includes a base plate and a top cover. The flow channel is for a liquid coolant and extends between an inlet connector and an outlet connector. The liquid coolant flows along a flow direction. The fin arrangement is located between the base plate and the top cover. The fin arrangement is thermally coupled to the flow channel and is eccentrically located relative to the cold plate module.

Abstract: An apparatus includes an overlay mark. The overlay mark includes a first portion including a first pattern and a second portion including a second pattern. The first pattern includes a plurality of first features and a first center feature each separated by a gap along a first direction. At least two gaps are the same but are different from the other gaps, and the first centers are symmetric with respect to the first center feature. The second pattern includes a plurality of second features and a second center feature each separated by a gap along the first direction. At least two gaps are the same but are different from the other gaps, and the second features are symmetric with respect to the second center feature. The first center feature of the first pattern is aligned with the second center feature of the second pattern along a second direction.
