Introducing the STEVAL-ISA196V1 from STMicroelectronics

The STEVAL-ISA196V1 is a state-of-the-art power management integrated circuit (PMIC) evaluation board, designed and manufactured by STMicroelectronics. This evaluation board is specifically tailored for designers and engineers looking to test and evaluate the performance of the L7986A, a highly efficient DC-DC converter. The L7986A is a step-down switching regulator capable of delivering up to 3A of continuous output current with excellent line and load regulation.

The STEVAL-ISA196V1 showcases the L7986A's wide input voltage range, from 4.5V to 38V, which makes it suitable for a diverse array of applications, including industrial control systems, consumer electronics, and automotive devices. The board is designed to demonstrate the low-power operation and minimal standby current of the L7986A, which are critical for battery-powered and energy-saving applications.

Equipped with an adjustable output voltage that can be set from 0.8V to the input voltage, the STEVAL-ISA196V1 provides the flexibility needed for design customization. The high switching frequency of the L7986A, which can be programmed up to 1MHz, allows for the use of small surface-mount inductors and capacitors, thereby reducing the overall solution size and cost.

For protection and reliability, the evaluation board includes features such as overcurrent protection, thermal shutdown, and a soft-start function to prevent inrush current during startup. The STEVAL-ISA196V1 also offers the benefit of pulse-by-pulse current limiting and overvoltage protection, ensuring safe operation under abnormal conditions.

The compact and user-friendly design of the STEVAL-ISA196V1 evaluation board makes it an ideal platform for quick prototyping and testing. It comes with test points that provide convenient access to all critical signals and parameters, making it easy to monitor the performance and functionality of the L7986A regulator in various conditions.

Whether you are developing power supplies for consumer electronics, exploring energy-efficient solutions, or working on industrial design, the STEVAL-ISA196V1 from STMicroelectronics provides a comprehensive and practical evaluation tool to accelerate your design process and achieve optimal power management performance.
