Power trends: Size is everything

May 22, 2018 // By Nick Flaherty
Smaller, more efficient power modules are increasingly in demand for a wide range of industrial automation applications. Nick Flaherty talks to Anil Telikepalli, executive director of business management at Maxim Integrated about the latest trends

“Technology in general has always been a race, and today, at this time, it is the race to be the smallest in its class,” said Anil Telikepalli, executive director of business management at Maxim Integrated (below).

The reason he says that is that Maxim has launched the smallest point of load (PoL) in its class, which in this case is relatively low current for the 42V uSLIC module as processor and IC power management companions. This has been made possible by some key packaging technology that allows 3D stacking of commercial inductors, allowing Maxim to combine its Himalaya power management chips with all the other components needed.

"We see mixed signal as the next frontier and integration is the play in a big way as we have integrated not only diverse analogue blocks with digital and mixed signal so uSLIC is a key investment from the company and this type of technology allows us to get a lot closer to the user. We will continue to drive that technology as we have seen more demand for other things that customers want us to do,” he said. “Can we push the envelope further, absolutely.”

He sees at least a 3.3x improvement in the power density going forwards. “What we are building here is a base framework for a range of products,” he said. “Most of the power modules have been focussed at lower voltages as IC companions as there are a lot more point of loads voltages than high voltage and focussed on ease of use for customers that are not power supply experts – they want a module with pre-selected magnetics, compensation and a certain input, output and current.”
