When working with the design of solar inverters, meeting a certain efficiency specification was mandatory to be competitive in the market.  This is a challenge, especially with 1200 V IGBTs, and required attention to every detail, from bus bar thickness to inductor core material.

Analog Devices has launched a 50A step-down µModule regulator with PMBus digital interface that stacks and exposes its two inductors on top of a BGA package for improved cooling.
