The STEVAL-ISA092V1 is a low-voltage application field and working principle evaluation board, designed to let users easily evaluate the low-voltage offline SMPS application field and working of the STP016R and STP082R. This evaluation board has been specifically designed to provide some help in the development and integration of the STP016R and STP082R devices.

The STEVAL-ISA092V1, based on the STP016R, integrates a flyback topology, which enables a very compact and easy-to-mount solution. It includes all the main components necessary for a full operation. It is an isolated design, suitable for a wide range of input voltages from 85 to 265 V AC, and accepts a full-mains range of inputs from both single-phase and two-phase applications. Up to 45 W can be delivered at the output. This board supports for open-loop control, requiring only an external resistor. The flyback converter is enabled using an external NPN transistor and its turn-off detection is ensured by an external current-sensing resistor. The STEVAL-ISA092V1 also includes a high-d visibility LED to indicate output power.

The STEVAL-ISA092V1 is easily configurable using an emerald multi-function interface and X-NUCLEO-IHM06A1 motor control board, and it also includes the integrated functionalities of the STP016R. This evaluation board also offers pre-defined values of output voltage, current and PWM frequency that allow a very accurate control over the flyback converter.

The board comes with an on-board resistor, snubber and demoblock that allows for a configurable output voltage, protecting the system against over/under-voltages. Thanks to the compact design, it can be used for both offline and online applications, while still offering the same performance as a larger and more expensive evaluation board.

The STEVAL-ISA092V1 evaluation board also offers a wide range of other features such as active power-factor correction, over-current protection, comparative safety certification, insulation measurement and temperature measurement. All these features offer better protection and control over the power-conversion process, making it a reliable and safe solution for a variety of commercial and industrial applications.

In conclusion, the STEVAL-ISA092V1 evaluation board is an ideal solution for evaluating the low-voltage SMPS application field and working principle, designed for both offline and online applications. It offers a wide range of features that provide superior protection and improved efficiency over traditional evaluation boards. This evaluation board allows for a quick and easy integration into the existing system with high performance levels.
