Claim 28:
29. A power converter having an input port and an output port, the power converter comprising:
a controller to generate one or more control signals based, at least in part, on signals within the power converter;
at least one switch to alternately transition between a conducting and a non-conducting state based, at least in part, on a gate-drive voltage to be applied to a gate of the at least one switch; and
a level shifter to control the at least one switch, wherein the level shifter is to store and select a first logical value that generates the gate-drive voltage in response to the one or more control signals, wherein a latch is to store information indicative of a preceding transition, wherein said level shifter comprises a delay that is to prevent said gate-drive voltage from changing until lapse of a blanking interval,
wherein the level shifter further comprises a first path and a second path, the first path and the second path providing complementary transitions between the conducting and non-conducting states, wherein the level shifter selects the faster of the first path and the second path after each transition.
