TDK-Lambda has expanded its DC-DC converter line-up with the introduction of the IQG Series, which provides high true useable power in an industry-standard quarter-brick footprint.

With up to 95 per cent efficiency and a maximum power rating of 300W, these supplies are suitable for tight-space, power-hungry applications with demanding thermal environments, such as ATCA-based communications equipment, where high reliability is critical.

The IQG Series is also suitable for various 48V-powered architectures as deployed in industrial, factory automation, robotics equipment and broadcast markets.

The converters are initially available as 12V models, with further products planned.

They offer up to 95 per cent power conversion efficiency and 180W/in3 power density and delivers up to 25A useable output current.

The monotonic start-up into a pre-bias output capability and high capacitive load enhances versatility, according to the company.

Throughout the open-frame, single-board construction, TDK-Lambda claims that attention has been paid to the overall thermal design, including component height, location and orientation.

As a result, the IQG Series is compatible with all cooling strategies, including contact, convection and forced air, and offers good thermal performance for cooler operation over its operating temperature range of -40C to +125C.

Furthermore, the proprietary TDK ASIC control circuitry – bringing a significant component-count reduction, improved reliability and lower cost – makes the IQG Series suitable as replacements or upgrades in legacy applications.

Standard features include: fixed-frequency operation; 1,500VDC input to output isolation; negative remote on/off; and the automatic recovery of input under voltage, output over current and over-temperature protection circuitry.

Options include: latching/non-latching protection; automatic-recovery output over voltage protection; positive polarity on/off; and the omission of a base plate.

Safety approvals for TDK-Lambda’s IQG Series include UL60950 (US and Canada), VDE 0805, the CB scheme (IEC950) and CE Mark (EN60950).
