8 Parameter Measurement Information

TPS22975 application_circuit_02_SLVSDD0.gif
A. Rise and fall times of the control signal are 100 ns.
B. Turnoff times and fall times are dependent on the time constant at the load. For the TPS22975, the internal pull-down resistance RPD is enabled when the switch is disabled. The time constant is (RPD || RL) × CL.
