Ultra thin 3A Step-Down DC/DC uModule Regulator [Chip Ideas]
posted January 13 2015 20:09.22 by Giorgos Lazaridis

On December 1st, 2014 Linear Technology Corporation introduced the LTM4623, a 3A uModule step-down regulator in an ultra thin 1.8mm profile LGA package with only a 6.25mm x 6.25mm footprint. With solder paste, the package height is less than 2mm, meeting the height restrictions of many PCIe (Peripheral Component Interconnect Express), Advanced Mezzanine Cards (AMC) for AdvancedTCA carrier cards in embedded computing systems.

The small size and low height allow the LTM4623 to be mounted on the backside of the PCB, freeing space on the topside for components such as memory and FPGAs. The LTM4623 operates from 4V to 20V input supplies and precisely regulates an output voltage from 0.6V to 5.5V with 1.5% maximum total DC output voltage error. Application examples include ultradense data storage, gateway controllers and 40Gbps to 100Gbps network equipment.
