STEVAL-ISA014V1 - STMicroelectronics

The STEVAL-ISA014V1 is a highly efficient, fully integrated power supply module from STMicroelectronics designed specifically for ease of use and rapid prototyping. This product is part of the evaluation series that allows designers and engineers to test and assess the features and capabilities of STMicroelectronics' advanced power solutions.

This evaluation board is built around the L5980, a step-down monolithic power switching regulator capable of delivering up to 1.5 A of continuous current at output voltages from 0.8 V to VIN. With a wide input voltage range from 4.5 V to 36 V, the STEVAL-ISA014V1 is versatile for a range of applications, including industrial control systems, embedded systems, and consumer electronics.

Key features of the STEVAL-ISA014V1 include:

• High efficiency, thanks to the L5980's low R<sub>DS(on) and optimized switching topology.
• Adjustable output voltage, allowing for a wide range of output configurations.
• Thermal protection and overcurrent protection, ensuring safe operation under various conditions.
• Frequency synchronization, which allows the reduction of radiated system noise that is critical for RF and sensitive analog applications.
• Compact size and minimal external components requirement, making it suitable for space-constrained applications.

The STEVAL-ISA014V1 is also equipped with an enable pin, which provides a simple on/off control and allows power sequencing. Its under-voltage lockout (UVLO) feature ensures that the device operates at the correct input voltage. Additionally, the soft-start function limits inrush current during startup, contributing to system reliability.

For developers and engineers looking to quickly implement a power solution or to evaluate the L5980 regulator, the STEVAL-ISA014V1 provides a convenient and flexible platform. Its performance and features can be easily tested and integrated into a variety of power-sensitive applications, making it an invaluable tool in the design and development process.
