Description

The LTM4601HV is a complete 12A step-down switch mode DC/DC power supply with onboard switching controller, MOSFETs, inductor and all support components. The µModule is housed in a small surface mount 15mm ×15mm × 2.8mm LGA package. Operating over an input voltage range of 4.5 to 28V, the LTM4601HV 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 (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 µModule 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 onboard differential remote sense amplifier can be used to accurately regulate an output voltage independent of load current.
