TPS54335AEVM-010 3-A Regulator Evaluation Module

Introduction

1 Introduction

1.1 Background

The TPS54335A dc/dc converter is designed to provide up to a 3-A output from an input voltage source of

4.5 V to 28 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 areas that may

be achieved when designing with the TPS54335A regulator. The switching frequency is externally set at a nominal 340 kHz. The high-side and low-side MOSFETs are incorporated inside the TPS54335A package along with the gate-drive circuitry. The low drain-to-source on resistance of the MOSFETs allow the TPS54335A to achieve high efficiencies and helps keep the junction temperature low at high output currents. The compensation components are external to the integrated circuit (IC), and an external divider allows for an adjustable output voltage. Additionally, the TPS54335A provides an adjustable undervoltage lockout input. The absolute maximum input voltage is 30 V for the TPS54335AEVM-010.

1.3 Modifications

These evaluation modules are designed to provide access to the features of the TPS54335A. Some modifications can be made to this module.

1.3.1 Output Voltage Set Point

The voltage divider, R7 and R8, is used to set the output voltage. To change the output voltage of the EVM, it is necessary to change the value of resistor R8. Changing the value of R8 can change the output voltage above 0.8 V. The value of R8 for a specific output voltage can be calculated using Equation 1. Use 100 kΩ for R7.

Table 3 lists the R9 and R10 values for some common output voltages. Note that VINmust be in a range

so that the minimum on-time is greater than 145 ns, and the maximum duty cycle is less than 100%. The values given in Table 3 are standard values, not the exact value calculated using Equation 1.

Figure 2 shows the efficiency for the TPS54335AEVM-010 on a semi-log scale to better show light load

efficiency. The ambient temperature is 25°C.

The efficiency may be lower at higher ambient temperatures, due to temperature variation in the drain-tosource resistance of the internal MOSFET.

2.9 Powering Up

Figure 11 and Figure 12 show the start-up waveforms for the TPS54335AEVM-010. In Figure 11, the

output voltage ramps up as soon as the input voltage reaches the UVLO threshold as set by the R1and R2 resistor divider network. In Figure 12, the input voltage is initially applied and the output is inhibited by using a jumper at JP1 to tie EN to GND. When the jumper is removed, EN is released. When the EN voltage reaches the enable-threshold voltage, the start-up sequence begins and the output voltage ramps up to the externally set value of 5 V. The input voltage for these plots is 24 V and the load is 5 Ω.

Board Layout

3 Board Layout

This section provides a description of the TPS54335AEVM-010, board layout, and layer illustrations.

3.1 Layout

Figure 15 through Figure 17 show the board layout for the TPS54335AEVM-010. The topside 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, V

connections for the remaining pins of the TPS54335A and a large area filled with ground. To facilitate the placement of the main input bypass capacitor as close to the VINand GND pins as possible, the trace for VPHASE is routed to the bottom layer immediately at the pin 3 connection. It is routed back to the top layer at the L1 inductor and C4 BOOT capacitor. The bottom layer contains a ground plane plus a copper fill area for VPHASE, an etch run to connect the upper resistor of the voltage set point divider to the regulation point at the J2 output connector, and a trace to connect the upper resistor of the UVLO set point divider network to VIN. The top-side ground areas are connected to the bottom and internal ground planes with multiple vias placed around the board including four vias directly under the TPS54335A device to provide a thermal path from the top-side ground area to the bottom-side and internal ground planes.

The input decoupling capacitors (C2, and C1) and bootstrap capacitor (C4) 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 BSR010 PCB is set up to accommodate both the TPS54335A and TPS54336A. For TPS54335A, the RT resistor R3 is used, while for TPS54336A, C3 is used to set the adjustable slow-start time. For the TPS54335A, an additional input bulk capacitor may be required, depending on the EVM connection to the input supply.
