Texas Instruments TPS62230EVM-574

Overview

TPS62230EVM-574 from Texas Instruments is an evaluation module designed to demonstrate and validate the performance of three independent TPS6223x 3-MHz synchronous step-down converters-U11 (2.5 V), U21 (1.8 V), and U31 (1.2 V)-each delivering up to 500 mA output current within a 2.05 V–6 V input range. It supports PWM and PFM mode selection, input/output voltage sensing, and enable control for rapid prototyping of multi-rail power systems in space-constrained applications.

For engineers reviewing the TPS62230EVM-574 datasheet, TPS62230EVM-574 setup, TPS62230EVM-574 board layout, or TPS62230EVM-574 schematic, this EVM provides verified reference designs, test-ready jumpers (ENABLE/Mode), dedicated VIN/VOUT/GND connectors per channel, and layout-optimized routing for high-frequency buck converter evaluation under real-world load and thermal conditions.

Technical Context

The TPS62230EVM-574 implements three isolated dc/dc channels using TI's TPS62230DRY (2.5 V), TPS62231DRY (1.8 V), and TPS62232DRY (1.2 V) ICs in 1×1.5 mm SON packages. Each channel features independent input/output sense lines, short-circuit protected operation, and selectable fixed-frequency PWM or efficiency-optimized PFM modes via JPX2 jumpers.

Board-level design follows TI's high-frequency switch-mode layout guidelines: minimized high-di/dt loop areas, ground-shielded VOUT traces, single-point grounding, and placement of 2.2 μF/4.7 μF 0402 ceramic capacitors and 1 μH 0805 inductors adjacent to each IC. Input bulk capacitance (C13/C23/C33) is provided as open pads for user-defined 1210-size capacitors.

FAQ

What is the primary purpose of the TPS62230EVM-574?

The TPS62230EVM-574 is an evaluation module built to characterize and validate the electrical performance, thermal behavior, and layout implementation of three TPS6223x synchronous buck converters operating at 3 MHz. It enables engineers to verify regulation accuracy, transient response, efficiency curves, and mode-switching behavior across varying loads without designing custom PCBs. The TPS62230EVM-574 includes all necessary passive components, jumpers, and test points aligned with TI's published data sheet test conditions.

Does the TPS62230EVM-574 support adjustable output voltages?

No-the TPS62230EVM-574 implements fixed-output configurations only: U11 delivers 2.5 V (TPS62230DRY), U21 delivers 1.8 V (TPS62231DRY), and U31 delivers 1.2 V (TPS62232DRY). These are factory-configured by resistor feedback networks on the board and are not user-adjustable via potentiometers or external resistors. To evaluate other output voltages, users must refer to the TPS6223x family data sheet (SLVS941) and modify feedback dividers accordingly-but such modifications are outside the validated scope of the TPS62230EVM-574.

How are the ENABLE and MODE functions implemented on the TPS62230EVM-574?

The TPS62230EVM-574 uses shunt jumpers for both ENABLE and MODE control on each of its three channels. JP11/JP21/JP31 connect the EN pin to either ON (high, enabling operation) or OFF (low, disabling output); floating EN is prohibited. JP12/JP22/JP32 tie the MODE pin to ON (PWM mode, fixed 3 MHz) or OFF (PFM mode, variable frequency for high light-load efficiency). These jumpers provide deterministic, low-risk configuration without soldering or external logic, ensuring reliable startup and mode selection during bench testing of the TPS62230EVM-574.

Can the TPS62230EVM-574 be used for compliance testing (e.g., FCC/ICES)?

No-the TPS62230EVM-574 is explicitly designated for engineering development, demonstration, and evaluation purposes only and is not certified for FCC Part 15 Class A/B or ICES-003 compliance. As stated in its User's Guide, it generates unfiltered RF energy and lacks shielding, filtering, or enclosure required for emissions certification. Users must integrate validated power stages into final system-level designs and perform full EMC testing per applicable standards-not rely on the TPS62230EVM-574 as a compliant subsystem.

What layout practices does the TPS62230EVM-574 demonstrate for high-frequency buck converters?

The TPS62230EVM-574 demonstrates TI-recommended high-frequency layout techniques: minimal hot-loop area between VIN, SW, and GND; ground-plane shielding of sensitive VOUT and FB traces; tight placement of 0402 input/output capacitors and 0805 inductors adjacent to each IC; and use of separate input/output sense paths routed away from noisy switching nodes. Its two-layer PCB (shown in Figures 1–3 of SLVU426A) implements these principles to minimize parasitic inductance and EMI-providing a proven reference for replicating robust 3-MHz buck performance in production designs using the TPS62230EVM-574 as a benchmark.
