30 Amp Half Brick DC-DC Converters Feature 93% Efficiency

Description

Lambda has expanded its line of DC-DC converters with the launch of the new iHG series of 100W fully isolated, single output, half-brick devices. Providing exceptional thermal performance, using the industry standard half-brick footprint with no base plate, the modules are ideal for engineers designing low airflow, high temperature, 48V power architectures, for telecom, wireless, medical, industrial and many other applications. The initial product offering includes 5V/10A, 5V/20A and 3.3V/30A devices, with further products planned.

The single board construction combined with up to 93% efficiency delivers a very high level of useable power in convection cooled environments, particularly where airflow rates are low. Furthermore, the all new digital control circuitry bringing a significant component count reduction, as well as improved reliability and lower cost, makes the iHG family well-suited as replacements or upgrades in legacy applications.

The iHG’s operate over a wide input range of from 36V to 75Vdc and feature a very wide output voltage adjustment/trim range from about 50% to 110% of its nominal output voltage. Operating temperatures can range from -40°C to +125°C, measured at the module.

In addition to high efficiency operation, the iHG’s very low input current consumption in its standby mode (typically only 4.8mA) demonstrates Lambda’s commitment to the “green” environmental issues of concern to all manufacturers today.

The input is fully isolated from the output, up to 1500Vdc, further adding to the product’s versatility by allowing different options for polarity and grounding connectivity. Standard features include fixed frequency operation (for reduced EMI), output trim, remote sense, remote on/off, and auto-recovery of input under voltage, output over current, over temperature and over voltage protection.

All units are RoHS compliant. Safety approvals for Lambda’s new iHG family include UL60950 (US and Canada), VDE 0805, CB scheme (IEC950) and CE Mark (EN60950).
