UCC27714EVM-551 is a multi-topology evaluation module (EVM) designed to evaluate the Texas Instruments high-performance, low-cost UCC27714 non-synchronous Boost\Flyback integrated circuit. The device has a wide range of applications in both offline and online switches mode power supply (SMPS).

The UCC27714EVM-551 evaluation board is designed to demonstrate the features and performance of the UCC27714 non-synchronous boost\flyback controller with a wide input voltage range of 90Vac to 265Vac and operating frequency up to 100KHz. It allows the user to evaluate the UCC27714 SMPS with different topologies, such as boost, flyback, forward with the same platform. It comes with multiple feature options such as thermal shutdown, overload protection, soft-start charging, edge-controlled start, auto restart mode. It also includes a controller with a standby mode and an adjustable peak current limit.

The input voltage of the UCC27714EVM-551 can range from 6 to 42V, with an output current of up to 750mA. The output voltage can be adjusted up to 45V with an accuracy of given by a low output voltage ripple. With the suitable external components, this EVM has the ability to evaluate low power applications (<5W) or higher power applications (>500W). The UCC27714EVM-551 evaluation board also has an adjustable switching frequency of 40KHz to 100KHz.

The board is supplied with several jumper areas which provide the user with the flexibility to design the SMPS for the purpose. Furthermore, the board has an internal DC supply for powering the EVM. The jumper areas and the on-board trimming options make the board suitable for both development & evaluation uses.

The device UCC27714 has an integrated frequency modulation (FM) and peak current limit (PCL) which helps in controlling and optimizing the conduction loss of the SMPS. The low on-resistance of the UCC27714 reduces the power dissipation of the SMPS and also ensures stable operation over the temperature and duty cycle ranges.

The UCC27714EVM-551 evaluation board can be used in a wide range of applications such as LED lighting, off-line DC/DC converters, DC/AC inverters, general-purpose power supplies, AC/DC adapters, mobile chargers. The board is highly integrated and designed to provide users with the best evaluation experience, allowing more efficient design and faster prototyping.

To sum it up, UCC27714EVM-551 is a versatile evaluation module with multifunction. It provides the user with the flexibility to design and evaluate SMPS with different topologies with the same platform. This makes it the best solution for development & evaluation of DC/DC & AC/DC (Off-Line) SMPS applications.
