100A PoLs have Digital Control and PMBus™ Communication
TDK Corporation has announced the introduction of the 100A TDK-Lambda iJC series of PoL (Point of Load) non-isolated dc-dc converters. Being PMBus™ compliant and featuring auto-tuning 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 14-Vdc input, the iJC series can provide output voltages from 0.6- to 1.5-V, 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 PMBusâ„¢ 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 PMBusâ„¢ communication is not implemented. A GUI (Graphical User Interface) and evaluation boards are available for development support.
