Background
The TPS55340 DC/DC converter is a step-up boost converter. Rated input voltage and output current
range for the evaluation module are given in Table 1. This EVM demonstrates the performance of the
TPS55340 in an example application and accommodates evaluation of other boost applications supported
by the TPS55340. This design shows that a small printed-circuit-board area is possible when designing
with the TPS55340 regulator. However, appropriate sizing of the inductor and diode for the desired
application can further reduce the board area. The switching frequency is externally set at a nominal 600
kHz. The 40-V, 5-A, low-side MOSFET is incorporated inside the TPS55340 package along with the gatedrive circuitry. The low drain-to-source on-resistance of the MOSFET achieves high efficiencies with the
TPS55340. The compensation components are external to the integrated circuit (IC). The absolute
maximum input voltage is 32 V for the EVM.

Modifications
These evaluation modules provide access to the features of the TPS55340. Some modifications to this
module are possible.
3.1
Output Voltage Set Point
The resistor divider network of R1 and R2 sets the output voltage. Keep R2 fixed at or close to 10 kΩ.
Change the output voltage of the EVM by changing the value of resistor R1. Calculate the value of R1 for
a specific output voltage by using Equation 1.
æ V
ö
R1 = R2 ´ ç OUT - 1÷
è 1.229V
ø
(1)
Note that VIN must be in a range so that the on-time is greater than the minimum controllable on-time (77
ns typical), and the maximum duty cycle is less than 89% minimum and 93% typical.
3.2
Maximum Output Current
After adjusting input or output voltage settings, verify the maximum output current pursuant to the
equations given on the data sheet.
3.3
Slow-Start Time
Adjust the slow-start time by changing the value of C3. The EVM uses C3 = 0.047 µF, as recommended
on the data sheet, avoiding any overshoot during start-up. A larger capacitance increases the slow-start
time while a smaller capacitance decreases it.
3.4
Other Modifications
Please see data sheet recommendations and equations when changing the switching frequency,
input/output voltage range, input inductor, output capacitors or compensation.

Test Setup and Results
This section describes how to properly connect, set up, and use the EVM. Included are test results typical
for the evaluation module covering efficiency, output voltage regulation, load transients, loop response,
output ripple, input ripple, start-up and shut-down.
4.1
Input/Output Connections
The EVM is provided with input and output connectors and test points as shown in Table 3. Connect a
power supply capable of supplying 5 A to J6 through a pair of 20 AWG wires. The jumper across JP1 in
the ON position (1-2) must be in place. Connect the load to J7 through a pair of 20 AWG wires. The
maximum load-current capability must be at least 1.9 A. Minimize wire lengths to reduce losses in the
wires. Header J1 provides a place to monitor the VIN input voltages with J3 providing a convenient ground
reference. Use J2 to monitor the output voltage with J4 as the ground reference.

Board Layout
This section provides a description of the EVM board layout and layer illustrations.
5.1
Layout
The board layout for the EVM is shown in Figure 17 through Figure 21. The top-side layer of the EVM is
laid out in a manner typical of a user application. The top, bottom, and internal layers are 2-oz. copper.
The top layer contains the main power traces for VIN, VOUT, and SW. Also on the top layer are connections
for the remaining pins of the TPS55340 and a large area filled with ground. The internal layers and bottom
are primarily ground with additional fill areas for VIN and VOUT. The top-side ground traces connect to the
bottom and internal ground planes with multiple vias placed around the board. Nine vias directly under the
TPS55340 device provide a thermal path from the top-side ground plane to the bottom-side ground plane.
Place the output decoupling capacitors (C8–C11) as close to the IC as possible. The copper area of the
SW node is kept small minimizing noise. The vias near the diode, D1, on the VOUT plane aid with thermal
dissipation. Additionally, keep the voltage setpoint resistor divider components close to the IC. The voltage
divider network ties to the output voltage at the point of regulation, the copper VOUT trace at the J7 output
connector. For the TPS55340, an additional input bulk capacitor may be necessary, depending on the
EVM connection to the input supply. Critical analog circuits such as the voltage setpoint divider, frequency
set resistor, slow-start capacitor, and compensation components terminate to ground using a separate
ground trace on the top and bottom connected power ground, pour only at one point directly under the IC.
