The STEVAL-ISA152V1 evaluation board is a evaluation board from STMicroelectronics for the study of DC/DC and AC/DC (Off-line) SMPS. This evaluation board features a family of PFCs ICs (Integrated Circuit) from the L6697A series. This SMPS evaluation board is therefore perfect for testing and factory plants testing, as well as for educational or research applications.

A SMPS (Switched-Mode Power Supply) is a power conversion technology that is widely used to supply electricity for electrical devices such as computers and home electronic equipment. It works by using an AC voltage of 220V and then converts it into a DC voltage of the desired amount. This is done by using different components, such as transistors, diodes and inductors, all of which are used to control the flow of the current to the output.

The STEVAL-ISA152V1 evaluation board is designed as a test platform to evaluate the features of the L6697A family ICs used in variable frequency applications. It has two different DC/DC converters, one for DC/DC low side and one for AC/DC (Off-line) high side.

The board is equipped with a size less than 60mmx40mm and its entire weight is around 27.3g. Moreover, it operates on an input voltage from 400VAC, adding to the versatility of the board. The input voltage range is adjustable between 180VAC and 440VAC, thanks to the integrated zero voltage switching (ZVS) control. Furthermore, it can even switch to different output current capacities with precision.

The board features two power factor corrector (PFC) circuits. The PFC circuits are used to convert the alternating current (AC) to direct current (DC). It does this by using active, or reactive, power to control and limit the current. As a result, the power factor of the AC supply is improved and the amount of noise generated is reduced. Additionally, the STEVAL-ISA152V1 evaluation board also includes an ER (Energy Recovery), a buck, boost and buck-boost power board.

The STEVAL-ISA152V1 evaluation board also features an analog feedback control loop, which allows the user to adjust the output voltage during operation. This control loop includes a microcontroller, an analog-to-digital (ADC) converter and a digital-to-analog (DAC) converter. By using these components, the user can adjust the output voltage on the fly depending on the load. Moreover, the board also includes a display which is used to set the output voltage and current levels.

The STEVAL-ISA152V1 evaluation board can be used in a variety of applications, such as powering industrial equipment, lighting applications, remote control systems, medical devices, home appliances, and many others. Its versatility makes it a great choice for any application where a reliable and efficient SMPS is needed.
