TDK-LAMBDA EXPANDS iHG FAMILY OF DOSA HALF BRICKS

Following on from the successful launch of the iHG Series of half brick DC-DC converters, TDK-Lambda has added new devices offering a wide input range (36-75V) with nominal outputs from 2.5V/80A (200W), 3.3V/30A (99W), 3.3V/70A (231W), 5V/10A (50W) and 5V/60A (300W). Providing exceptional thermal performance, using the industry standard DOSA half-brick footprint, the iHG Series is ideal for engineers designing low air flow, high temperature, 48V power architectures, for telecom, wireless and industrial applications.

The open frame, single board construction, with up to 92.5% efficiency, provides a very high level of useable power in convection cooled environments with very low levels of airflow. Furthermore, the innovative control circuitry brings considerable component count reduction, thereby improving reliability and lowering component and placement costs, as well as reducing its overall weight significantly. This makes the iHG family well-suited as replacements or upgrades in legacy applications, as well as new designs.

The fully regulated output voltage is trimmable over the very wide range of -50 to +110% and provides monotonic start up, even into pre biased and high capacitance loads. Further standard features include fixed frequency operation, 1500Vdc input to output isolation, remote sense and remote on/off, latching over voltage and non-latching input under voltage, overload and over temperature protection circuitry. Options include a baseplate and latching protection circuitry.

TDK-Lambda’s iHG Series is approved to a wide range of national and international safety standards, including UL60950 (US and Canada), VDE0805 and CB scheme (IEC950). In addition, this series carries the CE mark according to the LV Directive and comes with a three-year warranty.
