Abstract: Modulating a gate drive current supplied to an output drive switch coupled to an electric motor by performing at least the following: obtain a gate drive current modulation profile, supply, based on the gate drive current modulation profile, a first gate drive current level as the gate drive current when the output drive switch is operating within a first region, drop the first gate drive current level to a second gate drive current level when the output drive switch transitions from the first region to operating within a Miller region, increase the second gate drive current level to a third gate drive current level within the Miller region, and set the gate drive current to a fourth gate drive current level when the output drive switch transitions from the Miller region to operating within a third region.

Abstract: A modulation device may include a variable burst regulator and a current-driven clock generator. The modulation device may include a first output terminal configured to provide a modulated voltage for an operating frequency over a modulation period. The current-driven clock generator may include a second input terminal configured to receive a buffered version of the modulated voltage. The current-driven clock generator may include a second output terminal configured to provide a modulated current during the modulation period. The operating frequency may be proportional to the modulated current. The operating frequency may control the operating frequency over the modulation period.

Abstract: An integrated circuit (IC) assembly includes a first power stage adapted to receive an input voltage and a second power stage adapted to provide an isolated output voltage. The IC also includes a transformer coupled between the first and second power stages. The IC further includes a detuning circuit coupled to the transformer, and a receiver circuit coupled to the first power stage. The receiver circuit includes an integrator configured to integrate a switching signal within the first power stage.

Abstract: A rectifier circuit includes a first diode-connected transistor coupled to a first voltage terminal and a second diode-connected transistor coupled to a second voltage terminal. A switch network is coupled between the first diode-connected transistor and the second diode-connected transistor. The switch network has a first switch network terminal adapted to be coupled to a first terminal of a secondary winding of a transformer and has a second switch network terminal adapted to be coupled to a second terminal of the secondary winding of the transformer.
