FEATURES  
DESCRIPTION  
n
Complete Switch Mode Power Supply  
TheLTM®4601Aisacomplete12Astep-downswitchmode  
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  
continuouscurrent(14Apeak). Onlybulkinputandoutput  
capacitors are needed to complete the design.

UltraFast™ Transient Response  
The low profile and light weight package easily mounts  
on the back side of PC boards. The µModule regulator  
can be synchronized with an external clock for reducing  
undesirable frequency harmonics and allows PolyPhase®  
operation for high load currents.
