DESIGN PROCEDURE
TPS54010
SLVS509B – MAY 2004 – REVISED JUNE 2005
Figure 12. Application Circuit, 2.5 V to 1.5 V
shows
the
schematic
for
a
typical
TPS54010 application. The TPS54010 can provide
up to 14-A output current at a nominal output voltage
To begin the design process, a few parameters must
of 1.5 V. Nominal input voltages are 2.5 V for PVIN
be decided. The designer needs to know:
and 3.3 V for VIN. For proper thermal performance,
Input voltage range
the exposed PowerPAD underneath the device must
be soldered down to the printed-circuit board.
