Overview of LTM4601AIY#PBF

The LTM4601A 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 LTM4601A 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 20V, the LTM4601A 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.
