LTM4619 Datasheet - Linear Technology

DESCRIPTION
The LTM®4619 is a complete dual 4A step-down switching mode DC/DC power supply. Included in the package are the switching controller, power FETs, inductor, and all support components. Operating over input voltage ranges of 4.5V to 26.5V, the LTM4619 supports two outputs with voltage ranges of 0.8V to 5V, each set by a single external resistor. Its high efficiency design delivers 4A continuous current (5A peak) for each output.
