V(OUTS, GNDS) = 1.0V
RTIME = 71.5k
RTIME = 71.5k (12.5mV/μs nominal)
RTIME = 35.7k (25mV/μs nominal) to
178k (5mV/μs nominal)
Soft-start and soft-shutdown: RTIME =
35.7k (3.125mV/μs nominal) to 178k
(0.625mV/μs nominal)
Slow: VDPRSTP = VDPRSLPVR = 5V, 1/4
normal slew rate, RTIME = 35.7k (6.25mV/
μs nominal) to 178k (1.25mV/μs nominal)
