Overview
The LTM8003HY-3.3#PBF is a high-performance, 40VIN, 3.5A continuous step-down Silent Switcher µModule® (power module) regulator produced by Analog Devices Inc. This regulator is designed to minimize EMI while delivering high efficiency at frequencies up to 3MHz. The LTM8003 integrates the switching controller, power switches, inductor, and all support components into a compact package, making it ideal for high-density point-of-load regulation. The module operates over an input voltage range of 3.4V to 40V and supports an output voltage range of 0.97V to 18V, with a switching frequency range of 200kHz to 3MHz, set by a single resistor.
