Texas Instruments TPS566247EVM

Overview

TPS566247EVM from Texas Instruments is an evaluation module for the TPS566247 6-A synchronous buck converter, configured to deliver a fixed 1.05-V output across 3-V to 16-V input, operating in forced continuous conduction mode (FCCM) for stable light-load performance. It integrates the TPS566247DRLR IC in SOT-563, supports up to 6-A load current, features D-CAP3™ adaptive on-time control, and enables rapid validation of power stage efficiency, transient response, and ripple under real-world conditions.

For engineers reviewing the TPS566247EVM datasheet, TPS566247EVM pinout, TPS566247EVM application, or TPS566247EVM equivalent, this page delivers verified board-level specifications, test setup guidance, layout insights, and direct comparison with the TPS566242EVM - all critical for selecting the right evaluation platform for 1.05-V/6-A point-of-load designs in industrial, telecom, and embedded systems.

Technical Context

The TPS566247EVM implements a complete, ready-to-use synchronous step-down power stage centered on the TPS566247 IC, which uses D-CAP3™ control architecture optimized for low-ESR ceramic output capacitors and requires no external compensation. Its FCCM operation ensures constant 600-kHz switching frequency across load range, eliminating audible noise and simplifying EMI filtering compared to Eco-mode variants.

Board-level design includes 2-oz top/bottom copper layers, dedicated GND planes (1-oz), input/output decoupling with Murata GRM21BR61E106MA73L and GRM21BR61A226ME44L capacitors, and a Würth 744311100 1-µH shielded inductor rated for 15 A. Test points (TP2–TP13) and terminal blocks (J1/J2) support full characterization of line/load regulation, startup/shutdown timing, and 6-A transient response at 2.5 A/µs slew rate.

FAQ

What is the primary function of the TPS566247EVM?

The TPS566247EVM is a fully assembled evaluation module that demonstrates and validates the performance of the TPS566247 6-A synchronous buck converter. It provides a 1.05-V output from a 3-V to 16-V input, operates in FCCM mode for consistent light-load behavior, and includes test points, connectors, and layout optimized for efficiency, thermal management, and transient testing - enabling rapid power stage characterization without custom PCB design.

How does the TPS566247EVM differ from the TPS566242EVM?

The TPS566247EVM and TPS566242EVM share identical hardware layout and component selection but differ in firmware-level control behavior: the TPS566247EVM implements forced continuous conduction mode (FCCM), maintaining 600-kHz switching across all loads, while the TPS566242EVM uses Eco mode with variable frequency at light loads. This makes the TPS566247EVM preferable for noise-sensitive or EMI-critical applications where frequency stability is mandatory.

Can the output voltage of the TPS566247EVM be adjusted?

Yes, the output voltage of the TPS566247EVM can be adjusted by modifying the feedback resistor divider network - specifically resistors R4 (R_UPPER) and R5 (R_LOWER). The default 1.05-V setpoint is calculated using the TPS566247's internal 0.6-V reference; changing R4/R5 values per the device's voltage divider equation allows precise configuration across the supported 0.6-V to 7-V range without hardware redesign.

What test points are provided on the TPS566247EVM for performance validation?

The TPS566247EVM includes 13 labeled test points: TP1/TP2 monitor VIN, TP3/TP4 monitor VOUT, TP5/TP7/TP6/TP10/TP12/TP13 provide multiple ground references, TP8 accesses the switch node for waveform analysis, TP9 monitors EN signal, and TP11 supports loop response measurements. These enable comprehensive validation of startup/shutdown timing, line/load regulation, ripple, and transient response without soldering or probing sensitive traces.

Is the TPS566247EVM compatible with standard lab equipment?

Yes, the TPS566247EVM is fully compatible with standard bench equipment: J1 accepts 3–16-V DC input via 20-AWG wires, J2 delivers up to 6-A output to electronic loads or test fixtures, and all test points accept standard 1× or 10× passive probes. Its layout minimizes parasitic inductance, and its 2-oz copper layers ensure stable thermal and electrical performance during extended 6-A operation - making it directly usable in validation labs without adapters or modifications.
