TDK-Lambda’s iQG Series of dc/dc converters are for intermediate or distributed bus power architectures. Featuring a low profile package, 0.52 in. high, these converters have been designed with confined space and demanding thermal environments in mind for applications such as Datacom/Telecom, Wireless/Broadcast, Robotics, Industrial Controls and Test & Measurement. The iQG series provides a regulated 12VDC output with a high-isolation of 1500VDC, input to output.  In addition, they operate with an input range of 36 V to 75 V dc. Models are rated at 300 W or 400 W.

The converter’s efficiencies of up to 95% substantially minimize wasted heat and system cooling issues. Throughout the open frame, single board construction, particular attention has been made to the overall thermal design including component height, location and orientation. As a result, the iQG Series is compatible with all cooling strategies, including conduction, convection and forced air, and offers outstanding thermal performance for cooler operation over its operating baseplate temperature range of -40 to +125ºC.  Furthermore, the control circuitry brings a significant component count reduction, as well as improved reliability.

The monotonic start-up into a pre-bias output capability with its synchronous rectification enhances the converter’s versatility. Standard features include fixed frequency operation, remote on/off, and auto-recovery protection against input under voltage and output over current and over temperature.

The iQG 400 W units have a 230 W per cubic in.power density and deliver up to 33 A of useable output current. These models can be used individually or connected in parallel for higher power applications.

Safety approvals for the iQG series include UL60950-1 (US and Canada), VDE 0805, CB scheme (IEC60950-1), and the CE Mark.
