Quarter Brick DC-DC Converter Series Extended with New 504W Models

San Diego, CA – December 2015 –

TDK Corporation announces the introduction of an extension to the popular TDK-Lambda iQG series of DC-DC converters with new 504W models having efficiencies of up to 96.3%.  Operating from a 48Vdc nominal input, the quarter brick iQG range now includes 12V 42A outputs in addition to 300W and 400W rated parts.  With exceptionally high true useable power, the series is ideally suited for power-hungry, applications in demanding thermal environments.

Utilizing a dual cooling technique (thermal enhancement), the modules will deliver 38.5A (438W) in ambient temperatures of 55oC with airflow of 400 LFM.  With the addition of a 0.5” heat sink, it can deliver 504W at 70oC with airflow of 400 LFM. The dimensions follow the industry standard five pin quarter brick footprint of 57.9 x 36.8 x 12.9mm (typical).  Accepting an input voltage of 39V to 75Vdc, these additional iQG models maintain a tight output tolerance of +/-210mV (+/-1.7%) for all input, loading and temperature variations.

As an option, droop mode current share can be specified, allowing parallel operation to for additional output current.  Input-to-output isolation is 2,250Vdc (basic), and the converters are safety certified to UL/CSA/EN 60950-1 (2nd edition), carrying the CE mark in accordance with the LV Directive and RoHS Directives.

More information can be obtained at the following TDK-Lambda Americas website, http://www.us.tdk-lambda.com/lp/products/iqg-series.htm, or by calling 800-LAMBDA-4.  Product availability for the iQG series can be found via the link to TDK-Lambda’s distributor network (see “Check Distributor Stock to Buy”) at http://www.us.tdk-lambda.com/lp/.
