The STEVAL-ISA013V1 from STMicroelectronics is a highly efficient evaluation board designed for engineers and developers to assess the performance of the L6920DC high-efficiency step-up converter. This compact and versatile evaluation tool is perfect for applications requiring a regulated voltage supply from a single-cell Li-Ion battery or a 3-cell NiMH/NiCd battery.
The board operates on an input voltage ranging from 0.85V to 5.5V, making it ideal for portable applications where battery life is critical. The L6920DC chip itself is capable of providing a fixed output voltage of 3.3V or an adjustable output voltage from 2.5V to 5.5V, with a maximum output current of 200mA. Its high efficiency, reaching up to 96%, ensures minimal power loss during operation, thereby extending battery life.
Featuring a shutdown mode that reduces the quiescent current to less than 1µA, the STEVAL-ISA013V1 is tailored for battery-powered devices where every microampere counts. The board also includes an under-voltage lockout, thermal shutdown, and overcurrent protection, safeguarding both the evaluation board and the end application from potential damage due to abnormal operating conditions.
The evaluation board comes in a small package, offering a straightforward layout that simplifies testing and prototyping. It is equipped with test points that provide convenient access to all critical signals and parameters for thorough evaluation. Designers can quickly integrate the board into their existing projects to test the L6920DC performance without the need to develop a custom board from scratch.
In summary, the STEVAL-ISA013V1 is an invaluable tool for developers looking to create power-efficient designs with a reliable step-up voltage regulator. Whether for handheld devices, IoT applications, or any portable electronics, this evaluation board by STMicroelectronics offers a practical and efficient solution for power management challenges.
