TDK Corporation announces the introduction of the 35 Ampere TDK-Lambda iJA series of POL (Point of Load) non-isolated DC-DC converters. Being PMBus™ compliant and featuring digital control, these converters provide better 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 iJA series can provide output voltages from 0.6 to 3.3V, with a precision set point accuracy of 1%. 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 0.45 square inch of board space, representing an ultra-high power density of 580 Watts per cubic inch. Overall dimensions are 22.9mm x 12.7mm x 9.7mm with a weight of just 6.5g. Optimization of components using digital control enables a high current output in high temperature, low airflow environments. The iJA power module has a typical efficiency of 94% with a 3.3V 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 iJA 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.
