摘要： An inductor includes a core formed of a magnetic material and a foil winding wound at least partially around or through at least a portion of the core. A first end of the winding extends away from the core to form an extended output tongue configured and arranged to supplement or serve as a substitute for a printed circuit board foil trace. A second end of the winding forms a solder tab. At least a portion of the extended output tongue and the solder tab are formed at a same height relative to a bottom surface of the core. Another inductor includes a core formed of a magnetic material, a winding wound at least partially around or through at least a portion of the core, and a ground return conductor attached to the core. The core does not form a magnetic path loop around the ground return conductor.

摘要： A light source assembly includes multiple light emitters having output that are focused and mixed onto a optical fiber leading to an endoscope or other device. The emitters can be LEDs or solid state lasers that emit different colors. A driver circuit controls the relative output intensities of the light emitters so as to produce a desired light spectrum. A driver circuit includes a buck topology connected to a controller that provides current mode control. Pulse width modulation of the buck current is provided by a semiconductor switch across a solid state laser. A second order filter, formed by the an external inductor and the output capacitance of the buck topology, minimizes AC current ripple to the laser.
