Figure 29. Application Circuit, 3.3 V Output
Figure 29 shows the schematic for a typical
TPS54550 application. The TPS54550 can provide
up to 5-A output current at a nominal output voltage
of 3.3 V. For proper thermal performance, the
exposed PowerPAD underneath the device must be
soldered down to the printed circuit board.
DESIGN PROCEDURE
The following design procedure can be used to
select component values for the TPS54550.
Alternately, the SWIFT Designer Software may be
used to generate a complete design. The SWIFT
Designer Software uses an iterative design
procedure and accesses a comprehensive database
of components when generating a design. This
section presents a simplified discussion of the design
process.
To begin the design process a few parameters must
be decided upon. The designer needs to know the
following:
