The STEVAL-ISA001V1 is an evaluation board of the DC/DC & AC/DC (Off-Line) SMPS category. This device in-particular is a highly efficient converter, tailored to move a non-isolated output voltage of 88 volts with a high level of reliability and cost-effectiveness.

The STEVAL-ISA001V1 is based around two main components, an off-line controller, the ST1PS01, and an insulated gate bipolar transistor (IGBT). With a combined effort of these two components, the system is capable of supplying an output voltage up to 88V with an efficiency of 82.5%. The operating range of its input is 90-264V ac while the output is an adjustable voltage range from 40-60V DC, with a maximum load current of 6.35A.

The most notable feature of the STEVAL-ISA001V1 is that its controller can automatically detect whether the power input is sinusoidal or non-sinusoidal, and can also detect whether the connected load is resistive or capacitive in nature. This feature allows for the unit to understand how best to deliver its power and maintain control over the output.

Using the Closed Loop Control (CLC), the STEVAL-ISA001V1 is capable of regulating various parameters such as the input voltage, temperature, output voltage and output current. This feature of CLC provides fast response and is also capable of delivering excellent load regulation performance, even from low input line. The STEVAL-ISA001V1 also comes equipped with Over Current Protection (OCP), which prevents device destruction due to overloads and irregular power delivery.

Where the ST1PS01 off-line controller really shines is its ability to provide a high level of efficiency over a wide range of input and output voltages. This means the STEVAL-ISA001V1 can get as much as 82.5% efficiency at full load while providing an output voltage of 40V. Furthermore, when the load current decreases, the efficiency of the STEVAL-ISA001V1 only decreases by a mere 5% at 1.75A.

The STEVAL-ISA001V1 is also highly reliable when it comes to safety and reliability. It is designed to meet the requirements of many major safety and regulatory standards including UL, EN/IEC and RoHS. This means that in the event of an unsafe situation, the device will immediately shut down power and provide the user with a visual and audible warning.

Overall, the STEVAL-ISA001V1 provides a great level of control and efficiency when it comes to DC/DC & AC/DC (Off-Line) SMPS. With its reliable operation, wide range input and output voltages, and its advanced features, the STEVAL-ISA001V1 is a great device for high-end applications.
