Introducing the L6984TR from STMicroelectronics

The L6984TR is a high-efficiency, monolithic synchronous step-down regulator that is part of STMicroelectronics' extensive portfolio of voltage regulators designed to cater to a wide range of applications. This device is tailor-made for systems requiring a compact, high-performance power solution that can deliver up to 2A of continuous output current.

At the heart of the L6984TR is an advanced peak-current-mode control architecture that provides fast transient response and eases loop stabilization, allowing for a wide range of output capacitors and inductors. The regulator operates at a switching frequency of 2MHz, which minimizes the size of external components and helps in reducing the solution footprint on the PCB.

The L6984TR is highly versatile, with an input voltage range of 4V to 38V, making it suitable for a variety of applications from industrial to automotive environments. Its output voltage is adjustable from as low as 0.85V up to a maximum determined by the input voltage, ensuring compatibility with modern low-voltage digital ICs.

Efficiency is a hallmark of the L6984TR, boasting a low R<sub>DS(on) of internal power MOSFETs and a pulse skipping mode that reduces the switching frequency under light-load conditions, thus increasing efficiency. This feature is particularly beneficial for battery-powered applications where extending operation time is crucial.

The device is also packed with protection features to ensure reliable operation under adverse conditions. These include overcurrent protection, thermal shutdown, and a power good signal that provides real-time feedback on the output voltage status. Furthermore, the L6984TR has a soft-start feature that minimizes inrush current during startup, which is essential for preventing damage to sensitive components.

Available in a compact VFQFPN 16 (3x3 mm) package, the L6984TR is ideal for space-constrained applications. Its excellent thermal performance, combined with a wide temperature range, ensures stable operation across various environments.

Whether it's for powering microcontrollers, FPGAs, or other sensitive digital loads, the L6984TR from STMicroelectronics provides designers with a reliable, efficient, and flexible solution that meets the stringent requirements of modern electronic systems.
