Powervation Ltd. (San Jose, CA) has announced that its PV3012 digital controller is being used by new TDK-Lambda (Cork, Ireland) iJB Series high-current digital POL modules.

The iJB series products support low-voltage, high-current operation while providing ± 0.5% 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 full 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.

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 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® is the industry’s leading intelligent auto-tuning technology. The patented 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.

Specifications of iJB series include:

  • Input voltage range:12 V DC (8 to 14 V).
  • Output voltage range: 0.6 to 2.0 V.
  • Efficiency (typ.) Vo = 1.0 V: 89.5%.
  • Vo = 1.5 V: 92.0%.
  • Vo = 2.0 V: 93.0%.
  • Maximum output power: 120 W.
  • Mounting type: SMD.
  • Size (W x H x D): 26.8 x 9.7 (max.) x 24.1 mm.
