The ISL6531EVAL2 evaluation board is part of the Intersil family of control ICs. It is designed to provide a robust and reliable platform for testing and evaluating DC/DC and AC/DC (off-line) switch mode power supply (SMPS) applications. It is an off-the-shelf solution for a wide range of applications ranging from power adapters, PCMCIA cards, and smart cards to embedded and distributed systems.

The ISL6531EVAL2 is a 100 Watt evaluation board and is capable of delivering a maximum of 25 A current. The board is designed to work with the ISL6531EVAL in order to provide an evaluation platform for studying a range of switch mode power supplies in different topologies such as flyback, forward, CCM, burst mode, and adaptive burst mode. The board is built using the very same components as used in the actual power supply designs. This allows the user to quickly design, prototype, and test a power supply and perform a detailed evaluation before pilot production.

The ISL6531EVAL2 evaluation board ships with a range of components including the ISL6531 SMPS control IC, a transformer, a heat sink, an inductor, and the other necessary components for setting up and evaluating the power supply. The board also has a header socket ready for connection to a computer interface board. This allows the user to connect the board to a PC and control or monitor real-time performance. The evaluation board also comes with detailed reference documentation including application schematics, layout diagrams, component lists, technical notes, and bills of material.

The ISL6531EVAL2 has the capability to implement a range of feedback loops such as current mode, voltage mode, average current mode, and discontinuous current mode (DCM) control. The user can specify a separate amount of time for current sense and voltage sense, and can also adjust the current sense reference voltage according to the load. In addition, the evaluation board supports fixed frequency or step-by-step frequency and can be used to implement advanced functions such as synchronization, burst mode control, and soft start. The board also has a built-in OCP (overcurrent protection) circuit that is triggered when an overload situation is detected.

By utilizing the ISL6531EVAL2, engineers and designers can quickly and easily evaluate the efficacy of different design topologies, components, and design parameters. The evaluation board allows designers to experiment in real time situations without risking an expensive and time-consuming prototyping cycle. Additionally, the ISL6531EVAL2 supports a range of safety ratings including UL, IEC, and CSA certification. This makes it an excellent choice for high-power applications requiring dependable and reliable operation.
