SynQor Adds 9.6V 43A Bus Converter

97% Efficiency Offers Superior Derating Performance for IBA Applications

Boxborough, MA - August 23rd 2006 - SynQor announces the release of the BQ55090QPA40, an isolated step down Quarter Brick Converter within its BusQor range targeting Intermediate Bus Architectures (IBA). The unit can provide up to 43A of useable current at 6.5-11Vout from a 35-55V input voltage range. This unregulated device can be thought of as a DC Transformer with a ratio of 5:1 from input to output, hence supplying a nominal 9.6Vout at 48Vin.

The device sets itself apart from its competitors when considering the product's derating performance. With just 100LFM (0.5m/s) of airflow, the open-frame device can provide full current (43A) at up to 55degC ambient temperature. This is achieved in part as a result of the device's exceptional efficiency of 97%.

The BQ55090QPA40 is very scalable and multiple units can be directly paralleled to create higher power solutions. The unit provides basic isolation from input to output at a level of 2000Vdc. Protection features include input under-voltage lockout, output current limit, short circuit protection, and thermal shutdown. Operating temperature range is -40 to +100degC. The unit is available as fully RoHS compliant.

Sample and production quantities are available immediately with a stock to 8-week lead-time. The modules are priced at $63.20 in OEM quantities. For additional information, please contact your local SynQor representative.
