7.1 Test Circuit and Timing Waveforms Diagrams

A. Rise and fall times of the control signal are 100 ns.
B. Turn-off times and fall times are dependent on the time constant at the load. For the TPS7H2221-SEP, the internal pull-down resistance QOD is enabled when the switch is disabled. When QOD is connected to OUT using a resistor (RQOD), the time constant is (RQOD + RPD,QOD || ROUT) × COUT.
