LMZ31503RUQR Allgemeine Beschreibung

IV. Engineers and designers will appreciate the LMZ31503RUQR power module for its ease of use and high performance in power management applications. By integrating a 3-A DC/DC converter, power MOSFETs, shielded inductor, and passive components into a low profile QFN package, the LMZ31503RUQR simplifies the design process and minimizes the external component count, effectively eliminating the need for loop compensation and magnetics design. The device's 9×15×2.8 mm QFN package is designed for easy soldering onto a printed circuit board, enabling a compact point-of-load design with up to 95% efficiency and exceptional power dissipation, thanks to its thermal impedance of 13°C/W junction to ambient. Without the requirement for airflow, the LMZ31503RUQR can deliver the full 3-A rated output current even at high ambient temperatures, making it an excellent choice for powering performance DSPs and FPGAs in various applications. Its advanced packaging technology ensures a robust and reliable power solution, compatible with standard QFN mounting and testing techniques
