Description
General part information
LTM4644LTM4644-1 Series
The LTM4644/LTM4644-1 is a quad DC/DC step-down µModule (micromodule) regulator with 4A per output. Outputs can be paralleled in an array for up to 16A capability. Included in the package are the switching controllers, powerFETs, inductors and support components. Operating over an input voltage range of 4V to 14V or 2.375V to 14V with an external bias supply, the LTM4644/LTM4644-1 supports an output voltage range of 0.6V to 5.5V. Its high efficiency design delivers 4A continuous (5A peak) output current per channel. Only bulk input and output capacitors are needed.ApplicationsMultirail Point of Load RegulationFPGAs, DSPs and ASICs Applications
