STEVAL-ISA047V1 is an evaluation board with a number of AC/DC and DC/DC switch-mode power supply (SMPS) applications. It is designed to provide users with a complete SMPS solution that is both convenient and economical.

STEVAL-ISA047V1 is designed with a wide range of features and capabilities. It includes a wide working range of input voltages of up to 90-265 VAC at 0-75 Hz and a wide output voltage and current range of up to 200 W. It also offers advanced protection features such as overload, short-circuit and overtemperature protection as well as thermal shutdown accuracy.

The evaluation board is based on the ST IKS022V065E high voltage single-output vertical integration regulator (VIR), one of the Integrated Power Solutions series. This integrated switch-mode power supply includes an integrated low-power MOSFET as well as a pulse-width-modulated (PWM) controller and gate driver. The integrated MOSFET ensures lower switching loss and greater efficiency for improved energy savings.

The ST IKS022V065E is designed with a high efficiency, low component count and a wide input voltage range that is suitable for applications where limited space and weight savings are necessary. Additionally, it has a low-power operation, so it can be used in applications such as white goods, LED lighting or consumer electronics.

The evaluation board has a number of user-configurable parameters that can be set through a serial port interface or via the on-board potentiometers. These parameters include the output voltage, over-current protection level, and thermal shutdown threshold. Additionally, the board also offers an adjustable switching frequency, peak current limiting and remote ON/OFF control.

The evaluation board is designed to demonstrate the performance and features of the ST IKS022V065E in various AC/DC and DC/DC SMPS applications. It can be used to evaluate the performance of the device and can be utilized as a development platform for custom applications.

The working principle of STEVAL-ISA047V1 involves the action of the integrated MOSFET to convert a DC voltage to an AC voltage. When the MOSFET is energized, current flows in one direction through the primary winding of the power transformer. This generates a voltage across the secondary winding which is then rectified using the integrated Schottky diode to produce a DC voltage. The PWM controller then regulates the DC voltage using an internal current loop and produces the desired output voltage.

The STEVAL-ISA047V1 evaluation board is a helpful tool for quickly evaluating the suitability and performance of the ST IKS022V065E for various AC/DC and DC/DC SMPS applications. It offers a wide working range of input and output voltages, protection features as well as adjustable control parameters. It is an efficient, economical and convenient SMPS solution for both prototypes and custom designs.
