Overview
The LTM4647IY#PBF is a complete 30A output switching mode step-down DC/DC µModule® (power module) regulator produced by Analog Devices, Inc. This module integrates the switching controller, power FETs, inductor, and all supporting components into a single package, simplifying the design process and reducing the need for additional external components. It operates over an input voltage range of 4.7V to 15V and supports an output voltage range of 0.6V to 1.8V, adjustable via a single external resistor. The high efficiency design of the LTM4647IY#PBF delivers up to 87% efficiency from a 12V input to a 1.0V output with a 30A continuous load current. High switching frequency and a current mode architecture enable fast transient response to line and load changes without compromising stability.
