Patent ID: 8669750

Claim:
A power conversion circuit for providing a regulated output, comprising: a transistor having a gate, a first current carrying electrode and second current carrying electrode; wherein said first current carrying electrode of said transistor is configured to be connected to a voltage source; wherein said second current carrying electrode of said transistor is configured to be connected to a load; a gate driver circuit having an output connected to said gate of said transistor; said gate driver circuit having a bootstrap port; a switch circuit having a first port connected to said second current carrying electrode of said transistor; said switch circuit having a ground port configured to be connected to a ground; said switch circuit having a control port and a capacitor port; said switch circuit having a first configuration in which said capacitor port is connected to said first port; said switch circuit haying a second configuration in which said capacitor port is connected to said ground port responsively to the load being interrupted; wherein said switch circuit is responsive to a control signal received at said control port to transition between said first configuration and said second configuration; wherein said capacitor port of said switch circuit is configured to be connected to a first terminal of a capacitor; and wherein said bootstrap port of said gate driver circuit is configured to be connected to a second terminal of the capacitor.
