The LTM4601AHV is a complete 12A step-down switch mode DC/DC power supply with onboard switching controller, MOSFETs, inductor and all support components. The μModule regulator is housed in a small surface mount 15mm × 15mm × 2.82mm LGA or 15mm × 15mm × 3.42mm BGA package. The LTM4601AHV LGA and BGA packages are designed with redundant mounting pads to enhance solder-joint strength for extended temperature cycling endurance. Operating over an input voltage range of 4.5V to 28V, the LTM4601AHV supports an output voltage range of 0.6V to 5V as well as output voltage tracking and margining. The high efficiency design delivers 12A continuous current (14A peak). Only bulk input and output capacitors are needed to complete the design.The low profile and light weight package easily mounts in unused space on the back side of PC boards for high density point of load regulation. The μModule regulator can be synchronized with an external clock for reducing undesirable frequency harmonics and allows PolyPhase® operation for high load currents.An onboard differential remote sense amplifier can be used to accurately regulate an output voltage independent of load current. The LTM4601AHV is available with SnPb or RoHS compliant terminal finish.
