Patent ID: 7710168

Claim:
A circuit for a switching output, comprising: a first driver that is arranged to drive a power switch, wherein the first driver is arranged to begin to turn on the power switch if a first driver input signal changes from a first logic level to a second logic level, such that beginning to turn on the power switch causes an output voltage that is associated with the power switch to move toward a first pre-determined voltage level, wherein the first pre-determined level is reached when an edge of the output voltage is complete or approximately complete; a second driver that is arranged to drive the power switch; a slew detect circuit that is arranged to assert a slew detect circuit output signal when the output voltage reaches the first pre-determined level, wherein the slew detect circuit is arranged such that: if the first driver input signal corresponds to the second logic level: the second driver does not drive the power switch if the slew detect circuit output signal is unasserted, and the second driver drives the power switch if the slew detect circuit output signal is asserted; and a current source, wherein the first driver includes a first transistor that is coupled to the current source, and wherein the second driver includes second transistor that is coupled to the current source; wherein the first transistor has a first width-to-length (W/L) ratio, the second transistor has a second W/L ratio, and wherein the second W/L ratio is at least five times as great as the first W/L ratio.
