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 23. The bottom
layer of the board carries only ground potential for best performance. The layout also provides improved thermal
performance as the exposed lead frame is soldered to the PCB.
An evaluation module for the TPS60130 is available and can be ordered under product code
TPS60130EVM-143. The EVM uses the layout shown in Figure 23.

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.
