1 Introduction

This user's guide contains background information for the TPS54560 as well as support documentation for

the TPS54560EVM-515 evaluation module (PWR515). Also included are the performance specifications,

the schematic, and the bill of materials for the TPS54560EVM-515.

Figure 1. TPS54560EVM-515 Board

1.1 Background

The TPS54560 DC-DC converter is designed to provide up to a 5-A output current from an input voltage

source of 4.5 V to 60 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 TPS54560 regulator. The switching frequency is externally

set at a nominal 400 kHz. The high-side MOSFET is incorporated inside the TPS54560 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 TPS54560 provides an

adjustable undervoltage lockout with hysteresis through an external resistor divider. The maximum input

voltage is 60 V for the TPS54560EVM-515.

Test Setup and Results

1.4.1 Output Voltage Set Point

To adjust 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.

(1)

Table 3 lists the R5 values for some common output voltages assuming R6 = 10.2 kΩ. Note VIN must be in

a range so the minimum on-time is greater than 135 ns. The values given in Table 3 are standard 1%

values, not the exact value calculated using Equation 1.

1.8 12.7

2.5 21.5

3.3 31.6

5.0 53.6

12 143

Be aware, changing the output voltage can affect the loop response. It may be necessary to modify the

compensation components. Output capacitors with a higher output voltage may also be needed. Please

see the data sheet for details.

1.4.2 Adjustable UVLO

The undervoltage lockout (UVLO) can be adjusted externally using R1 (RUVLO1) and R2 (RUVLO2). The EVM

is set for a start voltage of 6.5 V and stop voltage of 5.0 V, using R1 = 442 kΩand R2 = 90.9 kΩ. Use

Equation 2 and Equation 3 to calculate the required resistor values for R3 and R4, respectively for

different start and stop voltages. The typical values of the constants in the two equations are as follows:

IHYS = 3.4 µA, VENA = 1.2 V, and I1= 1.2 µA.

2 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.

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 5 A must be connected to J2 through a pair of 20-AWG wires. If the power supply is

connected to the EVM using leads with length greater than 1 foot a bulk input capacitor is recommended

(C11). The load must be connected to J1 through a pair of 20-AWG wires. The maximum load-current

capability must be 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.

2.2 Efficiency

The efficiency of this EVM peaks at a load current of about 1.4 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. Measurements are taken at an ambient

temperature of 25 °C. The efficiency may be lower at higher ambient temperatures due to temperature

variation in the drain-to-source resistance of the internal MOSFET.

2.8 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 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 5 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 5 V.

In Figure 17 the input voltage is initially applied with EN held low. An external voltage of 3.3 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 5 V.

2.9 Shutdown

The shutdown waveforms are shown in Figure 18 and Figure 19. The input voltage for these plots is 12 V

with a 5-A resistive load. The top trace shows VIN, the middle trace shows EN, and the bottom trace shows

VOUT.InFigure 18 the input voltage is removed, and when the input falls below the undervoltage lockout

threshold, the TPS54560 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

TPS54560 is disabled, and the output voltage discharges to ground.

Figure 18. Shutdown With VIN Ramping Down Figure 19. Shutdown With EN Pulled Low

2.10 Low Dropout Operation

For improved low dropout operation, the TPS54560 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.

Board Layout

3 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 26. 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 TPS54560 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 TPS54560

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. In addition, the voltage set-point 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 TPS54560, an additional input

bulk capacitor may be required (11), depending on the EVM connection to the input supply.

3.2 Estimated Circuit Area

The estimated printed-circuit-board area for the components used in this design is 1.025 in2(661 mm2).

This area does not include test points or connectors. This design uses 0603 components for easy

modifications. The area can be reduced by using smaller-sized components.
