DC to DC Power Supplies (Converters)
POL Non-Isolated Converter (35 A) offers PMBus communication.
Press Release Summary:
Featuring digital control, iJA12035A007V operates from 8–14 Vdc input and can provide 0.6–3.3 Vdc output with set point accuracy of 1%. SMT design occupies 0.45 in.² of board space, resulting in 580 W/in.³ power density, and max output power is 100 W. Delivering up to 94% efficiency (3.3 V output, 12 V input, 80% loading), SMT DC/DC converters measure 22.9 x 12.7 x 9.7 mm and weigh 6.5 g. PMBus™ read-write functionality provides real-time, precision monitoring and parameter programmability.
Original Press Release:
35A POL Converter has PMBus(TM) Communication
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.
More information can be obtained at the following TDK-Lambda Americas website, http://www.us.tdk-lambda.com/lp/products/ijb-series.htm, or by calling 800-LAMBDA-4. Product availability for the iJA converters can be found via the link to TDK-Lambda’s distributor network (see “Check Distributor Stock”) at http://www.us.tdk-lambda.com/lp/.
