Overview
The LTM8003HY, produced by Analog Devices Inc., is a 40V input, 3.5A continuous step-down Silent Switcher µModule (power module) regulator. This device is part of the LTM8003 series and is designed to minimize EMI while delivering high efficiency at frequencies up to 3MHz. The module includes the switching controller, power switches, inductor, and all necessary support components, making it a complete step-down switch mode power supply. It operates over an input voltage range of 3.4V to 40V and supports an output voltage range of 0.97V to 18V. The compact, thermally enhanced BGA package is suitable for automated assembly and high-density point-of-load regulation.
