DC-DC converters for servers, routers, test, and measurement introduced by TDK
Jan. 26, 2016
SAN DIEGO, 26 Jan. 2016. TDK-Lambda Americas Inc. in San Diego is introducing 504-Watt versions of the company's TDK-Lambda iQG series of DC-DC converters for servers, routers, semiconductor manufacturing, test and measurement, and general industrial equipment.
The power electronics devices offer efficiencies to 96.3 percent. Operating from a 48-volt-DC nominal input, the quarter brick iQG range now includes 12-volt 42-amp outputs in addition to 300- and 400-Watt rated parts for power-hungry, applications in demanding thermal environments.
Using a dual-cooling technique, the modules will deliver 38.5 amps at 438 Watts in ambient temperatures of 55 degrees Celsius with airflow of 400 LFM. With the addition of a 0.5-inch heat sink, it can deliver 504-Watt at 70 degrees Celsius with airflow of 400 LFM.
The dimensions follow the industry standard five pin quarter brick footprint of 57.9 by 36.8 by 12.9 millimeters. Accepting an input voltage of 39 to 75 volts DC, these additional iQG models maintain a tight output tolerance of +/-210mV (+/-1.7 percent) 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 2,250-volt-DC (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.
