IPC: H02M3/158
CPC classification number: H03K17/162 , H02M1/08 , H02M3/1584 , H02M2003/1586
Abstract: A comparator sense input is disconnected from a current sense resistor for the duration of a switching transition in an adjacent channel(s). Instead, the sense input receives a signal of the magnitude and the slew rate sampled prior to the transition.
