Description

The LTM ®4601AHV is a complete 12AL step-down switch mode DC/DC power supply with onboard switching controller, MOSFETs, inductor and all support components. The Module is housed in a small surface mount 15mm * 15mm * 2.8mm LGA package. The LTM4601AHV LGA package is designed with redundant mounting pads to enhance solder-joint strength for extended temperature cycling endurance. Operating over an input voltage range of 4.5 to 28V, the LTM4601AHV supports an output voltage range of 0.6V to 5V as well as output voltage tracking and margining. The high effi ciency design delivers 12A continuous current (14A peak). Only bulk input and output capacitors are needed to complete the design.

The low profi le (2.8mm) and light weight (1.7g) package easily mounts in unused space on the back side of PC boards for high density point of load regulation. The Module 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 amplifi er of LTM4601AHV can be used to accurately regulate an output voltage independent of load current.
