PCB Layout Guidelines
TPS65136
www.ti.com ............................................................................................................................................................. SLVS831A – APRIL 2008 – REVISED JULY 2008
PCB layout is an important task in the power supply design. Good PCB layout minimizes EMI and allows very
good output voltage regulation. For the TPS65136, the following PCB layout guidelines are recommended.
Place the power components first. The inductor and the input and output capacitors must be as close as possible
to the IC pins. Place the bypass capacitor for the reference output voltage VAUX as close as possible to pin 4.
Use bold and wide traces for power traces connecting the inductor and input and output capacitors. Use a
common ground plane or a start ground connection.
See the TPS65136EVM-063 user's guide (SLVU244 ) and evaluation module for a PCB layout example.
