Abstract: Generally, this disclosure describes an apparatus. The apparatus includes switch controller circuitry. The switch controller circuitry includes dead time logic circuitry to determine an estimated dead time interval between a turn off of a first switch and a turn on of a second switch. The first switch and the second switch are coupled at a switched node. The estimated dead time interval is determined based, at least in part, on a difference between an input voltage, Vin, and a switched voltage, Vsw, detected at the switched node just prior to turning off the first switch, a parasitic capacitance, Cpar, associated with the switched node and a maximum inductor current, IL,max. The difference between Vin and Vsw represents the maximum inductor current.
