STEVAL-IFP023V1 is an evaluation and demonstration board and kit specifically designed for AC-DC power applications. This board and kit is perfect for creators and inventors who need a reliable platform to develop their projects. It simulates the crucial elements of power applications such as rectification, buck/boost topology, flyback topology, or LLC infrared remote control. This board and kit provides all of the essential elements needed for the successful development of a power application.

The AC-DC functionality of STEVAL-IFP023V1 is enabled by the use of high-power discontinuous conduction mode (DCM) buck-boost controller with valley-fill synchronization. It runs on a voltage range from 4.5V to 40V and can provide an output current up to 2A. The wide range of operation is enabled by adjustable parameters such as output voltage regulation, over-current protection, and over-temperature protection. The board also consists of an additional microcontroller performance monitor which allows users to monitor the productivity and health of the system.

The main applications of STEVAL-IFP023V1 evaluation board and kit include consumer electronics, lighting systems, industrial control, white goods, and renewable energy systems. The evaluation board comes with various built-in peripherals like DC power measurement board, system controller, 1xUSB interface, capacitive touch sensor, and energy monitoring board. The field of application for the evaluation board and kit can be extended to various other applications through the built-in expansion ports and other programmable settings.

The working principle behind STEVAL-IFP023V1 evaluation board and kit lies in its chip set that includes a primary AC-DC buck-boost rectifier and a secondary control board. The primary chip is an integrated high-power DCM buck-boost controller with valley-fill synchronization and a mini-driver, which features linearly proportional output voltage, over-current protection (OCP) and over-temperature protection (OTP) functions. The secondary board consists of a PWM programmable microcontroller (MCU) as part of the system controller, which can be used to monitor the rectifier’s performance. It also includes power supply monitoring, external voltage detection, capacitive touch sensing, and various expansion ports.

The DCM buck-boost controller has the ability to generate a buck current from the input voltage and to regulate the output voltage on the basis of the input current. By using the on-board control microcontroller, it is possible to adjust the output voltage according to specific application requirements. This dynamic adaptation of output voltage helps to maintain the efficiency of the circuit and optimize the power usage of the system. The over-current and over-temperature protection feature of the controller makes sure that the system does not enter into an unsafe operating region. Hence, the STEVAL-IFP023V1 evaluation board and kit is a reliable tool to evaluate and develop AC-DC power applications efficiently.
