TDK-Lambda chooses digital controllers from Powervation for POL power electronics modules

CORK, Ireland, 24 June 2014. Power electronics designers at TDK-Lambda Americas Inc. in San Diego needed digital controllers for the company's iJB series high-current digital point-of-load (POL) modules. They found their solution from Powervation Ltd. in Cork, Ireland.

The iJB series products support low-voltage, high-current operation while providing plus-or-minus 0.5 percent set-point accuracy over line, load, and temperature range.

While the PMBus functionality of the module provides real-time telemetry of voltage, current, and temperature and enables programmability of the DC-DC converter, the iJB series products also employ function setting pins, enabling them to be used in non-PMBus applications.

The target applications for the iJB series include: servers, routers and other Information & Communication Technology (ICT) equipment, T&M and industrial equipment.

"Using Powervation's intelligent auto-tuning technology, Auto-Control, the iJB POL modules bring better dynamic performance and system stability to the application -- autonomously managing circuit and load variations due temperature, component tolerances, ageing and board impedances," says David Norton, vice president of marketing at TDK-Lambda.

Powervation's Auto-Control is an intelligent auto-tuning technology that optimizes dynamic performance and system stability in real-time without requiring noise injection or the drawbacks of periodic techniques, company officials say.

This is a key benefit for modules and other designs that drive unknown or variable output loads, and addresses the challenges of load parameter drift that occurs over temperature and time.
