Texas Instruments TPS54560EVM-515

Overview

TPS54560EVM-515 from Texas Instruments is an evaluation module designed to demonstrate the TPS54560 60-V, 5-A step-down DC-DC converter in a compact PCB layout. It supports input voltages from 7 V to 60 V and delivers up to 5 A at 5 V output, operating at a nominal 400 kHz switching frequency with Eco-mode™ pulse-skipping for light-load efficiency.

For engineers reviewing the TPS54560EVM-515 datasheet, TPS54560EVM-515 test setup, TPS54560EVM-515 performance validation, or TPS54560EVM-515 loop response measurement, this EVM provides verified efficiency curves (peak 91.5% at 1.4 A), load transient response (±160 mV, 250 µs recovery), line regulation (±0.2%), and full design documentation including schematic, BOM, and layer layouts.

Technical Context

The TPS54560EVM-515 implements a non-synchronous buck topology using the TPS54560DDA IC in an 8-pin SON package, featuring internal high-side MOSFET, external compensation, and adjustable UVLO (6.5 V start / 5.0 V stop). It supports CCM and DCM operation, with measured loop bandwidth of 22 kHz and 61° phase margin at 12 V input and 5 A load.

Key design features include low-dropout operation via integrated low-side MOSFET for BOOT capacitor recharge, prebias start-up capability, and configurable output voltage (5 V default, adjustable from 0.8 V) using external resistor divider R5/R6. Input ripple is characterized at 480 mVpp (CCM, 5 A), while output ripple is 5 mVpp (CCM, 5 A).

FAQ

What is the primary function of the TPS54560EVM-515?

The TPS54560EVM-515 is an evaluation module for the TPS54560 step-down DC-DC converter, enabling engineers to validate performance, characterize efficiency, measure transient response, and verify layout practices. It is not a production-ready power supply but a fully documented reference platform supporting input voltages from 7 V to 60 V and delivering up to 5 A at 5 V. The TPS54560EVM-515 includes test points, jumpers, and schematics aligned with TI's SLVU863 User's Guide.

Does the TPS54560EVM-515 support adjustable output voltage?

Yes, the TPS54560EVM-515 supports adjustable output voltage via external resistor divider R5/R6. By changing R5 (RHS) while keeping R6 fixed at 10.2 kΩ, the output can be set to common values including 1.8 V, 2.5 V, 3.3 V, 5.0 V, or 12 V - with 5.0 V as the factory-default configuration. Equation 1 in the SLVU863 User's Guide defines the relationship, and Table 3 lists standard 1% resistor values. The TPS54560EVM-515's minimum output is constrained by the IC's 0.8 V internal reference.

What are the key performance metrics validated on the TPS54560EVM-515?

The TPS54560EVM-515 has been tested for peak efficiency (91.5% at 12 V input, 1.4 A load), load transient response (±160 mV deviation, 250 µs recovery), line regulation (±0.2%), output ripple (5 mVpp in CCM), loop bandwidth (22 kHz), and phase margin (61°). These metrics are measured per Table 2 of SLVU863 under controlled conditions (25°C ambient, specified input/output). The TPS54560EVM-515 also demonstrates Eco-mode™ operation down to 25 mA and DCM threshold at 400 mA.

Can the TPS54560EVM-515 be used for prebias start-up evaluation?

Yes, the TPS54560EVM-515 supports prebias start-up evaluation, as confirmed in Figure 17 of the SLVU863 User's Guide. When EN is pulled high while VOUT is externally biased to 3.3 V, the internal reference ramps from 0 V during soft-start, and regulation begins once the FB pin voltage reaches the internal reference level. This behavior is enabled by the TPS54560DDA IC's architecture and is fully implemented on the TPS54560EVM-515 board with appropriate test points (TP3, TP4, TP6, TP7) and jumper J3 for EN control.

Is the TPS54560EVM-515 FCC-compliant for emissions testing?

No - the TPS54560EVM-515 is explicitly designated for engineering development, demonstration, or evaluation only and is not certified for FCC Part 15 compliance. As stated in the regulatory notice of the SLVU863 User's Guide, it generates and radiates RF energy without formal emissions testing. Users must implement appropriate shielding, filtering, and layout controls if integrating into a final product. The TPS54560EVM-515 does not carry FCC or ICES-003 certification markings and is not intended for consumer deployment without additional compliance validation.
