Description

The LTM®4601A is a complete 12A 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 LTM4601A 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 20V, the LTM4601A 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 of LTM4601A-1 easily mounts on the back side of PC boards. 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 can be used to accurately regulate an output voltage independent of load current. The onboard remote sense amplifi er is not available in the LTM4601A-1.
