Introduction
This user's guide contains background information for the TPS54341 as well as support documentation for
the TPS54341EVM-555 evaluation module (PWR555). Also included are the performance specifications,
the schematic, and the bill of materials for the TPS54341EVM-555.

1.1
Background
The TPS54341 DC-DC converter is designed to provide up to a 3.5-A output from an input voltage source
of 4.5 V to 42 V. Rated input voltage and output current range for the evaluation module are given in
Table 1. This evaluation module is designed to demonstrate the small, printed-circuit-board (PCB) areas
that may be achieved when designing with the TPS54341 regulator. The switching frequency is externally
set at a nominal 400 kHz. The high-side MOSFET is incorporated inside the TPS54341 package along
with the gate-drive circuitry. The compensation components are external to the integrated circuit (IC), and
an external resistor divider allows for an adjustable output voltage. Additionally, the TPS54341 provides an
adjustable undervoltage lockout with hysteresis through an external resistor divider at the EN pin and
adjustable soft-start with an external capacitor at the SS/TR pin. The SS/TR pin can also be used to have
the output voltage track an external reference. Lastly, the PWRGD pin is an integrated open drain output
power good signal. The absolute maximum input voltage is 42 V for the TPS54341EVM-555.

Modifications
These evaluation modules are designed to provide access to the features of the TPS54341. Some
modifications can be made to this module. Component selection for modifications can be done with the aid
of WEBENCH or the excel spreadsheet (SLVC452) located on the product page.
1.4.1
Output Voltage Set Point
To change the output voltage of the EVM, the value of resistor R5 (RHS) should be changed while keeping
R6 (RLS) fixed. The output voltage can be adjusted to a minimum of the 0.8 V internal reference. The value
of R5 for a specific output voltage can be calculated using Equation 1:
æ Vout - 0.8V ö
RHS = RLS ´ ç
÷
0.8 V
è
ø
(1)
Table 3 lists the R5 values for some common output voltages assuming R6 = 10.2 kΩ. Note VIN must be in
a range to keep the on time greater than the minimum on-time. The values given in Table 3 are standard
1% values, not the exact value calculated using Equation 1.

Test Setup and Results
This section describes how to properly connect, set up, and use the EVM. The section also includes test
results typical for the EVM covering efficiency, output voltage regulation, load transients, loop response,
output ripple, input ripple, start up, and shutdown. Measurements were taken at an ambient temperature
of 25°C.
2.1
I/O Connections
This EVM includes I/O connectors and test points as shown in Table 4. A power supply capable of
supplying at least 3.5 A must be connected to J2 through a pair of 20-AWG wires. The load must be
connected to J1 through a pair of 20-AWG wires. The maximum load-current capability must be 3.5 A.
Wire lengths must be minimized to reduce losses in the wires. Test-point TP1 provides a place to monitor
the VIN input voltages with TP2 providing a convenient ground reference. TP3 is used to monitor the output
voltage with TP4 as the ground reference.

Efficiency
The efficiency of this EVM peaks at a load current of about 0.8 A with VIN = 12 V, and then decreases as
the load current increases towards full load. Figure 3 shows the efficiency for the EVM. Figure 4 shows
the light-load efficiency for the EVM using a semi-log scale. The efficiency may be lower at higher ambient
temperatures due to temperature variation in the drain-to-source resistance of the internal MOSFET.

Start Up
The start up waveforms are shown in Figure 15, Figure 16, and Figure 17. The input voltage for these
plots is 12 V with a 3.5-A resistive load. In Figure 15, the top trace shows VIN, the middle trace shows EN,
and the bottom trace shows VOUT. The input voltage is initially applied, and when the input reaches the
undervoltage lockout threshold, the start up sequence begins and the output ramps up toward the set
value of 3.3 V.
In Figure 16 the input voltage is initially applied with EN held low. When EN is released, the start up
sequence begins and the output ramps up toward the set value of 3.3 V.
In Figure 17 the input voltage is initially applied with EN held low. An external voltage of 1.8 V is supplied
to VOUT. When EN is released, the start up sequence begins and the internal reference ramps up from 0 V
with the internal soft-start. When the internal reference reaches the FB voltage the output begins ramping
toward the set value of 3.3 V.

The shutdown waveforms are shown in Figure 18 and Figure 19. The input voltage for these plots is 12 V
with a 3.5-A resistive load. The top trace shows VIN, the middle trace shows EN, and the bottom trace
shows VOUT. In Figure 18 the input voltage is removed, and when the input falls below the undervoltage
lockout threshold, the TPS54341 shuts down and the output falls to ground.
In Figure 19, the input voltage is held at 12 V, and EN is shorted to ground. When EN is grounded, the
TPS54341 is disabled, and the output voltage discharges to ground.

2.10 Low Dropout Operation
For improved low dropout operation, the TPS54341 includes a small integrated low-side MOSFET to pull
SW to GND when the BOOT to SW voltage drops below 2.1 V. This recharges the BOOT capacitor for
driving the high-side MOSFET. Figure 20 shows the steady state operation and Figure 21 shows the start
up and shutdown in a low dropout condition. Both measurements are taken with a 5-V output.

Board Layout
This section provides a description of the EVM, board layout, and layer illustrations.
3.1
Layout
The board layout for the EVM is shown in Figure 22 through Figure 25. The top-side layer of the EVM is
laid out in a manner typical of a user application. The top and bottom 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 TPS54341 and a large area filled with ground. The bottom layer contains
ground and a signal route for the bootstrap capacitor. The top and bottom and internal ground traces are
connected with multiple vias placed around the board including six vias directly under the TPS54341
device to provide a thermal path from the top-side ground plane to the bottom-side ground plane.
The input decoupling capacitors (C1–C3, C10), bootstrap capacitor (C4), and frequency set resistor (R3)
are all located as close to the IC as possible. To reduce noise on the PWRGD signal, the PWRGD traces
and pull up resistor (R8) are kept away from the switching node at the SW pin. In addition, the voltage setpoint resistor divider components are also kept close to the IC. The voltage divider network ties to the
output voltage at the point of regulation, the copper VOUT trace past the output connector (J1). For the
TPS54341, an additional input bulk capacitor may be required (C11), depending on the EVM connection
to the input supply.
