TDK Corporation announces the introduction of the 100A TDK-Lambda iJC series of POL (Point of Load) non-isolated DC-DC converters. Being PMBus™ compliant and featuring digital control, these converters providebetter dynamic performance, improved system stability and  allow a great deal of flexibility and customization to the end application’s needs.

Operating from an 8 to 14VDC input, the iJC series can provide output voltages from 0.6 to 1.5V, with a precision set point accuracy of 0.5%.  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 1.5 square inch of board space, representing an ultra-high current density of 66 Amps per cubic inch.  Overall dimensions are 28mm x 35mm x 10mm with a weight of just 20g.  Optimization of components using digital control enables a high current output in high temperature, low airflow environments.  The iJC power module has a typical efficiency of 91.5% with a 1.5V output, 12V input and 80% loading.

The PMBus™ read-write functionality of the converter provides real-time, precision monitoring of voltage, current and temperature, and allows full programmability of the iJC parameters.  Function setting pins make them easy to use in applications where PMBus™ communication is not implemented.  A GUI (Graphical User Interface) and evaluation boards are available for development support.
