【Three DC/DC Power Supply Evaluation Boards to Meet Diverse Design Requirements】

TI's DC/DC evaluation boards primarily cover three major categories of power products: DC/DC regulators, DC/DC converters, and DC/DC power modules, each type catering to different application scenarios and design needs.

DC/DC regulator evaluation boards are primarily aimed at highly integrated power solutions. These evaluation boards typically include all necessary passive components and feedback networks, enabling immediate deployment.

For instance, TPS54335AEVM-010 evaluation module provides a complete circuit for evaluating the TPS54335A synchronous buck SWIFT converter. This EVM converts input voltages ranging from 8V to 28V into a regulated 5V output, delivering up to 2A of maximum output current.

DC/DC converter evaluation boards are more suited to controller chips requiring external power devices. These boards demonstrate how to correctly configure and control the converter's operating parameters.

For instance, UCC28711EVM-160 evaluation module assesses the UCC28711 constant voltage, constant current primary-side regulated PWM controller. Designed for 5W off-line USB adapters, this board converts 90V to 265V RMS input voltage into 5V DC output.

DC/DC power module evaluation boards deliver complete isolated power solutions. These boards integrate all necessary components—including transformers, inductors, and power devices—to form a comprehensive power system.

DCP012415DB is 1W, 1000VRMS isolated non-regulated DC/DC converter module. It provides a complete power isolation solution suitable for applications requiring high isolation voltage.

【Typical Applications】

Within consumer electronics power design, TI evaluation boards provide rapid validation platforms. For instance, the TLV62095 evaluation board features DCS Control technology, delivering up to 4A output current—ideal for modern mobile device requirements.

Its high efficiency (up to 95%) extends battery life, making it an excellent choice for power designs in portable devices such as smartphones and tablets.

Industrial power systems similarly benefit from TI evaluation boards. LM706A0QEVM evaluation module is specifically designed for regulated or unregulated high-voltage input power rails ranging from 8V to 65V, maintaining a stable 3.3V output voltage even at load currents up to 10A.

This wide VIN range DC/DC solution offers an exceptionally large rated voltage and operating margin, capable of withstanding power rail voltage transients commonly encountered in industrial environments.

For automotive electronics applications, evaluation boards such as TLV9051-Q1 meet the stringent requirements of automotive-grade products. These boards account for the unique characteristics of automotive electronics environments—including high temperature fluctuations, vibration, and electromagnetic compatibility concerns—assisting engineers in designing power systems compliant with automotive standards.

High-density power design represents another key application area for TI evaluation boards. The LM706A0-Q1 high-density evaluation module demonstrates how to achieve high-efficiency power conversion within constrained spaces.
