The STEVAL-ILL069V1 is an evaluation board from STMicroelectronics suitable for use in the design, evaluation and testing of DC/DC and AC/DC (off-line) Switch Mode Power Supplies (SMPS). It is intended to provide designers and engineers with the necessary tools to quickly evaluate the performance of the STMicroelectronics range of SMPS controllers and features integrated components such as transformers, heatsinks, inductors and even AC filters.

The STEVAL-ILL069V1 is a single-in/single-out board featuring most of the components necessary for a complete SMPS design. The board is based around the VIPer22A high-voltage PWM controller from STMicroelectronics, capable of delivering up to 25 watts in applications such as LED drivers, chargers, fans and other household appliances. The VIPer22A is a high-performance and cost-effective solution for a wide range of low to medium power requirements, allowing quick and easy evaluation of its features.

The STEVAL-ILL069V1 is a powerful evaluation board for the VIPer22A PWM controller. It includes components such as a the STTM04L-2-1M3 transformer for improved power efficiency and durability in design, a STTH30L30K heatsink for improved thermal management, an STSW-ILL042 software package for easy configuration and tuning of the controller, and even an ADLCAP01-360 acoustic filter for improved immunity to acoustic noise. The board has been optimized to minimize component count and reduce cost by integrating many components, meaning engineers can quickly and easily evaluate the full features of the controller.

To assist in evaluation of the STEVAL-ILL069V1, there is a range of documentation supplied by STMicroelectronics. This includes the STEVAL-ILL069V1 user manual, presenting a detailed overview of board features and capabilities, as well as data sheets for the VIPer22A PWM controller and all other components supplied on the board. The user manual also includes information about the STSW-ILL042 software package, allowing engineers to quickly adjust the settings of the board to their own requirements.

In operation, the STEVAL-ILL069V1 is powered by an AC input line, with a wide range of voltages supported from as low as 85V AC up to 265V AC. During evaluation the board can be configured for single-output or dual-output operation, with user-specified switching frequency, input current limit and soft start configuration. The STEVAL-ILL069V1 also features an open loop gain selector for setting the compensation of the regulator and protection features such as short-circuit protection and thermal shutdown.

In conclusion, the STEVAL-ILL069V1 evaluation board from STMicroelectronics provides designers and engineers with an easy to use and cost-effective platform for the evaluation of the VIPer22A PWM controller. The board is capable of single-output or dual-output operation, with protection features and adjustable parameters allowing easy adjustment of the board for different designs. The STEVAL-ILL069V1 is an ideal solution for designers who are in need of a high performance and cost effective SMPS solution.
