Figure 12. Application Circuit, 3.3 V to 1.5 V
shows
the
schematic
for
a
typical
Output voltage
TPS54073 application. The TPS54073 provides up to
Input ripple voltage
14-A output current at a nominal output voltage of
Output ripple voltage
1.5 V. Nominal input voltages are 3.3 V for PVIN, and
Output current rating
3.3 V for VIN. For proper thermal performance, the
Operating frequency
exposed PowerPAD underneath the device must be
soldered to the printed-circuit board.
For this design example, use the following as the
input parameters:
The following design procedure is used to select
component values for the TPS54073. Alternately, the
