Patent number: 10250249Abstract: A circuit and method are provided for recuperating energy and decreasing driver power consumption in a switching converter. An inductor is directly connected between a gate driver and a gate electrode of a switch.

Patent number: 9742262Abstract: A power converter startup circuit establishes an operating voltage for control circuitry during startup and is then disabled to reduce no-load power dissipation. The startup circuit has a normally on characteristic to automatically provide startup charging current for a startup capacitor. The control circuitry begins operating as the startup capacitor voltage reaches an operating value, and it generates an inhibitory signal that disables the startup circuit to stop the startup charging current and reduce power dissipation. The normally on characteristic is achieved by an emitter switched current source employing a normally on device such as a depletion-mode J-FET. A resistor divider network provides both biasing for the startup current source and a point of monitoring the power supply input voltage during steady state operation. A charge pump provides a voltage of the inhibitory control signal sufficiently above the auxiliary voltage to turn off the normally on switching transistor.Type: GrantFiled: May 6, 2016Date of Patent: August 22, 2017Assignee: Bel Fuse (Macao Commerical Offshore) LimitedInventor: Mark Jutras
