SynQor (Hudson, MA) introduced a low-profile, quarter-brick-sized, isolated, dc/dc converter for low-power applications. The PowerQor Mega Series quarter-brick can deliver up to 15A of total output current at 3.3V and below, and 75W at 5V and above, without the need for an attached heatsink. The Mega quarter-brick series also offers a low profile of less than 8.5mm (0.33in).
The QML Series has a 48V nominal input (35V to 75V range) and meets input-voltage transient requirements up to 100V for 100ms. Employing the industry-standard quarter-brick footprint and pin out, the unit measures 1.45in x 2.3in (36.8mm x 58.4mm) and has a low profile of only 8.5mm. The module uses synchronous rectification to achieve high efficiency, resulting in no derating of output power up to 70 degrees C.
Production quantities of the 3.3Vout QML Mega quarter-brick converters will be available in February 2002. The modules are priced at $68.50 in 1,000-unit quantities. Additional output voltages of 1.5V, 1.8V, and 2.5V and 5V (all rated to 15A) will be available in the second quarter of 2002.
