Abstract: A multi-phase regulator circuit includes one or more switching converter circuits. Each switching converter circuit includes a transformer including a primary winding and a multi-segment secondary winding, a primary side switch circuit configured to connect the primary winding to an input of the multi-phase regulator circuit, and multiple secondary side circuits including multiple coupled-inductor circuits. Each coupled-inductor circuit includes a first winding magnetically coupled to a second winding. Each segment of the transformer multi-segment secondary winding is operatively coupled to the first winding of a coupled-inductor circuit and each of the first windings is connected to an output of the multi-phase regulator circuit.

Abstract: Techniques to achieve higher power/shorter pulses with a laser diode. By initially applying a static reverse bias across the laser diode, the laser diode can turn on at a larger inductor current. When the laser diode is initially reverse biased, depletion charge and diffusion charge can be populated before the laser diode will lase. This causes the laser diode to initially turn on at a larger inductor current, which will reduce the rise time, thereby achieving higher power/shorter pulses.
