The LTM®4616 is a complete dual 2-phase 8A per channel switch mode DC/DC power regulator system in a 15mm × 15mm surface mount LGA or BGA 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 LTM4616 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.
The low profile package enables utilization of unused space on the back side of PC boards for high density point-ofload regulation.
Fault protection features include overvoltage protection, overcurrent protection and thermal shutdown. The power module is offered in space saving and thermally enhanced 15mm × 15mm × 2.82mm LGA and 15mm × 15mm × 3.42mm BGA packages. The LTM4616 is available with SnPb (BGA) or RoHS compliant terminal finish.
