TDK and Powervation deliver 60-A Digital POL with PMBus

TDK Corporation today introduced the 60-A TDK-Lambda iJB series of Point of Load (PoL) dc-dc converters. Featuring intelligent auto-tuning technology, these converters provide better dynamic performance, improved system stability and extremely accurate current read-back. Operating from an 8 to 14Vdc input, the iJB series can provide output voltages of 0.6 to 2V, with a precision set point accuracy of 0.5%. The PV3012 digital controller from Powervation, Ltd. is being used by new TDK-Lambda iJB PoLs. The series is designed to meet a wide range of applications, including servers, routers and other Information & Communication Technology (ICT) equipment, semiconductor manufacturing equipment, measuring equipment and general industrial equipment.

The surface mount converters occupy only one square inch of board space, representing an industry-leading current density. Optimization of components using digital control enables high current output in high temperature environments. It can provide an output of 2Vdc with 93% efficiency, for a 120W power rating.

Comments David Norton, Vice President of Marketing, TDK-Lambda Americas Inc.: "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."

Powervation's Auto-Control® adaptive compensation technology optimizes dynamic performance and system stability in real-time without requiring any noise injection or the drawbacks of periodic techniques. 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.

Comments Powervation's CEO, Mike McAuliffe: "TDK- Lambda's iJB series delivers industry-leading power density with this 60 A solution requiring only one square inch of board space. Optimized system and component design and deployment of the advanced digital control features provided by Powervation's PV3012, has resulted in higher efficiency & reliability, faster transient performance and precision voltage control over all conditions."

The PMBus functionality of the converter provides real-time monitoring of voltage, current and temperature, and allows full programmability of the iJB parameters. Function setting pins makes them easy to use in applications where PMBus commination is not implemented, including parallel operation. A GUI (Graphical User Interface) is available for development support.
