SynQor Introduces 54V Converter To Drive PoE Applications

Boxborough, Mass. - May 3rd 2006 - SynQor is pleased to announce the release of a 54V, 5.1A output half brick DC-DC converter, broadening still further its range of products to satisfy the power demands of IEEE 802.3af compliant Power Over LAN and VoIP applications. The PQ55540HTL05 (open frame version) and PQ55540HTM05 (base-plated version) converters use synchronous rectification and SynQor's patented topology to achieve extremely high efficiencies, low power dissipation and high reliability, in a single board, open-frame or base-plated package (optional). With an optimized input voltage range of 38-55V, and operating at an exceptional 93% efficiency, the open frame device can supply up to 230W at 55C ambient with just 200LFM (1m/s) of forced air-cooling. For those applications requiring even more output power, the base-plated option allows the addition of a heatsink to increase the available power to the full 275W rating.

In keeping with the requirements of IEEE 802.3af, the device has a basic isolation level from input to output of 2250Vdc, and the design has been optimized to minimize common mode noise. The trim range of -20% to +5% adds additional flexibility for the user to adjust to their desired output voltage. Other control and protection features include remote sense, input UVLO, output OVP, current limit, short circuit, and thermal shutdown.

Sample and production quantities are available immediately with a stock to 8-week lead-time. The modules are priced at $87.00 in OEM quantities for the open frame version. For additional information, please contact your local SynQor representative.
