TPS2378EVM-602

Evaluation and demonstration boards and kits provide an essential service for engineers to test, evaluate, and demonstrate efficiency, performance, and operation of different types of circuitry and systems. The TPS2378EVM-602 is one such evaluation, demonstration board, and kit that offers engineers a way to study the functionalities of a unique TPS2378 solution with an added boost converter/PFC topology.

TPS2378EVM-602 is a low-cost and small-form-factor power supply designed to evaluate the TI TPS2378 family of primary-side-regulated FET controllers. This evaluation module provides a complete power solution for a Boost/Flyback converter used in an AC/DC power adapter, specifically with the TPS2378 in a PFC/PWM control topology. It also includes an integrated, floating 60V NMOSFET, sense resistor, and an on-board bulk storage capacitor. The evaluation module utilizes PDIP-8 packaging to save board space and cost.

This evaluation module is fixed at a voltage of 12VDC, providing the user with a regulated output of 19V, and offers multiple protection features, including over-voltage protection (OVP), under voltage protection (UVP) and short circuit protection (SCP). The module also features an adjustable current limit that enables the boost output power to be adjusted based on the application\'s demands. The module also works with a wide range of input voltage levels, allowing it to be used in a variety of applications.

The TPS2378EVM-602 evaluation module is primarily used in applications such as LED lighting, medical lighting, and industrial lighting, as well as other consumer electronics including portable or home entertainment systems. Its highly integrated design makes it ideal for such applications, as it is easy to use and has a low total bill of material cost.

The TPS2378EVM-602 evaluation module kit also provides a working principle to the user. By combining TI\'s TPS2378 family of primary-side-regulated FET controllers, an on-board 60V floating NMOSFET, the integrated switch-mode power supply works by the controller detecting the input voltage and current and then driving the floating NMOSFET to generate the corresponding output voltage and current, with the added boost converter/PFC topology providing a higher level of efficiency to the system and allowing for higher precision control. To protect the user against over-voltage, under-voltage and short-circuit conditions, an adjustable current limit is also provided.

In conclusion, the TPS2378EVM-602 evaluation module is an excellent solution for engineers for testing, evaluating, and demonstrating the efficiency, performance, and operation of different types of primary-side-regulated FET controllers and other circuitry and systems. With an integrated floating 60V NMOSFET, sense resistor, and bulk storage capacitor, this low-cost and small‑form-factor power supply offers engineers a convenient way to study the power solutions available with the TPS2378 family of controllers, and its adjustable current limit ensures higher precision control and protection during operation.
