STEVAL-ISA197V1 Evaluation Board from STMicroelectronics

The STEVAL-ISA197V1 is a highly efficient, compact, and versatile evaluation board designed by STMicroelectronics. This product is particularly tailored for testing and prototyping with the L7987, a high-performance 61 V, 3 A step-down switching regulator. The L7987 is capable of meeting the rigorous requirements of various applications, including industrial, consumer, and computer sectors, due to its wide input voltage range and high current capability.

The board operates over a broad input voltage range from 4.5 V to 61 V, making it suitable for use in systems with fluctuating supply voltages. It delivers a stable and adjustable output voltage that can be set from 0.8 V to VIN, with a maximum output current of 3 A, ensuring a reliable power supply for a wide range of components and devices.

With its high switching frequency, which is adjustable up to 1 MHz, the STEVAL-ISA197V1 allows designers to optimize the size of external components, resulting in a compact and space-saving solution. This feature is particularly advantageous in space-constrained applications. The board also includes an array of protection features such as overcurrent protection, thermal shutdown, and short-circuit protection, enhancing the reliability and longevity of both the evaluation board and the end application.

The STEVAL-ISA197V1 is equipped with an enable pin that allows power sequencing and power saving in standby mode. Additionally, the soft-start feature limits the inrush current at startup, which is beneficial for applications sensitive to high startup currents.

The evaluation board is designed with an eye toward ease of use. It comes with test points that provide convenient access to all critical signals and pins, making it simple to integrate into a development environment. Moreover, the STEVAL-ISA197V1 is supported by comprehensive technical documentation, including schematics, bill of materials, and application notes, which facilitate a smooth and rapid design process.

Overall, the STEVAL-ISA197V1 is an excellent choice for engineers and designers looking to evaluate the L7987 regulator and develop power supply solutions that require a high-performance, adjustable, and reliable step-down converter.
