The UCC28910FBEVM-526 evaluation board can be categorized as an off-line DC/DC and AC/DC switched-mode power supply (SMPS). It is a 5V, 9A, 40V input power supply evaluation module system-on-a-chip (SOC) with over-voltage, over-temperature, and current limit protection features. This evaluation board is ideal for test and evaluation of applications such as point-of-load (PoL) converters, universal AC/DC adapters, HDD power applications, battery charger designs, and other high-power SMPS designs.

The UCC28910FBEVM-526 consists of two main components: the UCC28910, a synchronous-rectification, multi-mode current mode controller for offline, AC/DC applications; and the companion controller UCC28061, a 72V, 15A high- and low-side gate drivers with integrated current sensing on its high-side rail.

The UCC28910FBEVM-526 operates in either an AC/DC or a DC/DC converter mode, depending on the user’s requirements. The board includes four configurations, allowing for a wide range of applications. In the DC/DC configuration, up to 9A can be achieved in an off-line, AC/DC converter. In the AC/DC configuration, up to 6A can be achieved. A peak current of 24A can be provided. The UCC28910FBEVM-526 allows efficient low-saturation current, low-dropout operation, and robust current-mode control with a minimum of components and low cost.

The UCC28910FBEVM-526 is a complete evaluation board designed to evaluate the application, performance, and design of applications based on the UCC28910 and UCC28061 controller ICs. The board features include an input voltage range of 8-40V, output voltage range of 4-5V, a maximum output current up to 9A, an efficiency of over 90%, and a wide range of protective features. The board also includes an over-current and over-temperature protection to maintain safe operation at all times. The UCC28910FBEVM-526 also includes a wide range of other features such as soft-start, cycle-by-cycle current limit, and short-circuit protection.

The UCC28910FBEVM-526 also includes features and capabilities such as programmable power-on reset and adjustable switching frequency, as well as a current share circuit for up to two inductors. It also has dynamic voltage scaling for applications where the input or output voltage needs to be varied.

The UCC28910FBEVM-526 is capable of many high-performance power supply designs. It enables a wide range of development and evaluation of design techniques. The evaluation board provides flexibility and a range of features to aid in the design and development of efficient and reliable switched-mode power supplies. The comprehensive test features and a highly reliable design ensure reliable operation of the UCC28910FBEVM-526 in a wide range of applications.
