SynQor Unveils PQ30 QGA Series DC-DC Converters

SynQor Inc. (Boxborough, MA) unveiled its new PQ30 QGA Series of dc-dc converters that have been specifically designed to help meet the challenging power requirements demanded by UMTS and CDMA base stations and wireless IP routers. By optimizing the converter design to meet the ETSI-required input-voltage range of 60 V (maximum) for 48 V systems, while also being able to operate as low as 18 V for 24 V systems, the quarter-brick unit can deliver 3.3 V at 25 A in demanding environmental conditions.

The performance of the PQ30 QGA means that no de-rating is necessary up to 70 °C ambient temperature with 200 LFM (1.0 m/s) of forced-air cooling; at 85 °C, the converter with the same level of forced-air cooling can deliver around 23 A. The increase in useable power over previous-generation products means that in one application, system designers have been able to maximize the channel element capacities for UMTS and CDMA applications with only one single quarter-brick converter.

The PQ30 QGA quarter bricks are capable of withstanding transients on the input to 80 V for 100 ms, and have a basic isolation level from input to output of 2,000 Vdc. Control and protection features include remote-sense, voltage trim, input under-voltage lockout, output over-voltage protection, current limit, short circuit and thermal shutdown. The operating temperature range is from 40 °C to +100 °C.

Sample and production quantities are now available, with a lead time from stock to eight weeks. The modules are priced at $58 in OEM quantities.
