The ISL8273MEVAL1Z is a reliable and efficient power supply and a popular choice for a wide variety of electronic products. The evaluation board provides a tested and proven platform for powering up a board or system quickly. This board can be used to study, debug or test applications involving a wide range of DC/DC and AC/DC switched-mode power supplies (SMPS). It is configured with an external transformer, allowing users to configure the primary side circuit to meet their specific needs. The evaluation board includes integrated circuitry to allow for the selection of both isolated and non-isolated designs.

The ISL8273MEVAL1Z evaluation board includes a power supply controller IC, the ISL8273M. This IC is a two-phase, high-efficiency, non-isolated, synchronous buck converter that provides continuous output current up to 7A with 1% accuracy. It is designed to drive the high-efficiency buck regulator with an external transformer for low-side current sensing, eliminating the need for an isolated feedback circuit. The output current limit is adjustable via external resistors, allowing for a wide range of output voltage regulation.

The ISL8273M IC provides excellent protection features such as over-current protection, under-voltage lockout, and short-circuit protection. It also includes adjustable frequency control, allowing users to select a frequency that accommodates their application’s load and switch characteristics. In addition, the IC offers built-in ripple/noise gating feature. This allows the SMPS to adjust the frequency to reduce output voltage ripple under light load conditions, eliminating the need for an external LC filter.

The evaluation board comes with an easy-to-use graphical user interface (GUI). This GUI can be used to quickly configure the ISL8273M IC, debug, and analyze the SMPS under different load conditions. The GUI also allows for the easy generation of control signals and PWM waveforms, as well as the viewing of real-time waveforms. This simplifies the process of evaluating and debugging the SMPS.

The ISL8273MEVAL1Z evaluation board is an ideal choice for testing the performance of DC/DC and AC/DC SMPS. Its wide range of protection features, adjustable frequency control, and easy-to-use GUI make it a great choice for low-power switching power supplies. The board is capable of providing reliable and efficient power to a wide variety of applications, making it a popular choice among power supply designers.
