Product Summary
The LTM4616V is a complete dual 2-phase 8A per channel switch mode DC/DC power regulator system in a 15mm ×15mm surface mount LGA package. Included in the package are the switching controller, power FETs, inductor and all support components. Operating from an input voltage range of 2.7V to 5.5V, the LTM4616V supports two outputs within a voltage range of 0.6V to 5V, each set by a single external resistor. This high efficiency design delivers up to 8A continuous current (10A peak) for each output. Only bulk input and output capacitors are needed, depending on ripple requirement. The part can also be configured for a 2-phase single output at up to 16A.
