APPLICATION INFORMATION
board layout
Careful board layout is necessary due to the high transient currents and switching frequency of the converter.
All capacitors should be soldered in close proximity to the IC. Connect ground and power ground pins through
a short, low-impedance trace. A PCB layout proposal for a two-layer board is given in Figure 27. The bottom
layer of the board carries only ground potential for best performance.
An evaluation module for the TPS60120 is available and can be ordered under product code
TPS60120EVM–142. The EVM uses the layout shown in Figure 27. The layout also provides improved thermal
performance as the exposed leadframe of the PowerPAD package can be soldered to the PCB.

The best performance of the converter is achieved with the additional bypass capacitors C5 and C6 at input and
output. Capacitor C7 should be included if the large line transients are expected. The capacitors are not
required. They can be omitted in most applications.
