Switching Frequency Limitations
Due to the internal design of the TPS543526 there are
limitations to the maximum usable switching frequency for
any given input voltage. This limit is constrained by the
minimum controllable on time which may be as high as
220 ns. Figure 31 shows the maximum switching
frequency versus input voltage for each device. This family
of curves is valid for output currents greater than 0.5 A. As
output currents decrease towards no load (0 A), the
apparent on time increases, decreasing the maximum
switching frequency that may be obtained for a given input
and output voltage. Figure 32 shows the maximum
switching frequency versus input voltage for each device
for zero load current various operating frequencies.
