Modifications
The TPS54372EVM-215 is designed to demonstrate the small size that can
be attained when designing with the TPS54372. Many
of the features that
allow for extensive modifications have been omitted from this EVM. The output
voltage V
(TTQ)
can be set in the range of 6% of V
I
to 1.75 V by changing the
V
(DDQ)
voltage input at J3. The output V
(TTQ)
will track at one half the V
(DDQ)
voltage. The lower voltage limit is set by the minimum on time of the
TPS54372. The upper voltage limit is set by the internal voltage reference.
Larger output voltages up to 90% of V
I
are possible in designs using the
TPS54372, but are not supported on this evaluation module.
The switching frequency may be trimmed to any value between 280 kHz and
700 kHz by changing the value of R5. Decreasing the switching frequency
results in increased output ripple unless the value of L1 is increased. A plot of
the value of RT versus the switching frequency is given in Figure 1
