Modifications
1.3.1
General
The TPS54310 EVM is designed to demonstrate the small amount of board
space taken up by the TPS54310 electrical components. In addition, the EVM
can be used to evaluate different output filters by substituting an alternate
inductor for L1, or by using the optional pads for capacitors C2 and C11 (see
Figure 3
–
1). When changing the output filter, the compensation values must
also be changed to ensure that stability is maintained. The SWIFT Designer
software tool or Texas Instruments application note SLVA109 can be used to
assist in the calculation of compensation components. Both SWIFT Designer
and SLVA109 are available for download at the Texas Instruments web site.
1.3.2
Switching Frequency
The TPS54310 is configured to switch at a frequency of 700 kHz. Alternatively,
the EVM can be easily configured to switch at either 350 kHz or 550 kHz by
removing the frequency trimming resistor R3, and placing the shunt on jumper
JP1 in the proper location. Also, by changing the value of RT (R3), the switch-
ing frequency can be trimmed to any value between 280 kHz and 700 kHz. A
plot of the value of RT versus the switching frequency is given in Figure 1
