STMicroelectronics L6982CDR - High-Efficiency Step-Down Converter

The L6982CDR is a highly integrated, synchronous step-down switching regulator from STMicroelectronics, designed to deliver efficiency and robustness for a wide range of applications. With its compact QFN-16 (3x3 mm) package, it is an excellent solution for space-constrained applications requiring efficient power management.

This advanced power solution operates from a wide input voltage range of 4 V to 38 V, making it versatile for various systems, including industrial, consumer, and automotive applications. The L6982CDR supports an adjustable output voltage that can be set from as low as 0.85 V to a maximum determined by the input voltage, catering to the needs of low-power devices and systems.

One of the key features of the L6982CDR is its high efficiency, which is achieved through synchronous rectification and a low quiescent current. The peak efficiency reaches up to 94%, ensuring minimal power loss during conversion, which is critical for energy-sensitive designs. Furthermore, the device offers a 2 A continuous output current capability, providing sufficient power for a variety of loads.

The L6982CDR also includes a wealth of protection features to safeguard your application. These features include overcurrent protection, thermal shutdown, and a power good flag that signals when the output voltage is within the regulation limits. Additionally, the soft-start function minimizes inrush current during startup, contributing to the stability of the power supply.

For design flexibility, the L6982CDR offers both high-frequency switching, which reduces the size of external components, and a low switching frequency option for applications where noise sensitivity is paramount. The device is also compatible with ceramic capacitors, which further reduces the overall footprint and enhances reliability.

In summary, the STMicroelectronics L6982CDR is a compact, efficient, and reliable step-down converter that meets the demands of modern electronic systems. Its comprehensive feature set and flexibility make it an ideal choice for designers looking to optimize power management in their products.
