LTM4644IY#PBF

LTM4644IY#PBF 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. Typical applications include multirail point of load regulation, FPGAs, DSPs and ASICs applications.
