LTM4601-1 Description

The LTM4601 is a complete 12A step-down switch mode DC/DC power supply with on-board switching controller, MOSFETs, inductor and all support components. The μModule® regulator is housed in small surface mount 15mm × 15mm × 2.82mm LGA and 15mm × 15mm × 3.42mm BGA packages. Operating over an input voltage range of 4.5V to 20V, the LTM4601 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.

A high switching frequency and adaptive on-time current mode architecture deliver a very fast transient response to line and load changes without sacrificing stability. An on-board differential remote sense amplifier can be used to accurately regulate an output voltage independent of load current. The on-board remote sense amplifier is not available in the LTM4601-1.
