APPLICATION INFORMATION
Figure 12. Typical Application Schematic
STEP BY STEP DESIGN PROCEDURE
The following design procedure can be used to select component values for the TPS54332. Alternately, the
SwitcherProSoftware may be used to generate a complete design. The SwitcherPro 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:
Input voltage range
Output voltage
Input ripple voltage
Output ripple voltage
Output current rating
Operating frequency
For this design example, use the following as the input parameters
Table 3. Design Parameters
DESIGN PARAMETER
EXAMPLE VALUE
Input voltage range
5 V to 15 V
Output voltage
2.5 V
Input ripple voltage
200 mV
Output ripple voltage
20 mV
Output current rating
3.5 A
Operating Frequency
1 MHz
SWITCHING FREQUENCY
The switching frequency for the TPS54332 is fixed at 1 MHz.
