SynQor Announces 40 Amp PowerQor Half-brick DC-DC Converters


Hudson, Mass - SynQor announces the expansion of their PowerQor鈩 series of high efficiency, no-heatsink required, isolated DC-DC converters to include five "half-brick" sized units that can deliver 40 amps of output current. With full load efficiencies ranging from 89% for the 3.3V output converter to 82% for the 1.5V output converter, these 48V input units dissipate far less heat than competing products and therefore do not require a heatsink to keep their components cool. SynQor is the first manufacturer to provide 40A DC-DC converters in a half-brick, no heatsink required format.

As output voltages rapidly shift from the traditional 5 volt standard to 3.3 volts and lower, design engineers will require higher output currents at lower voltages to provide sufficient power to their circuits. Additionally, board space is becoming more precious and card pitches are shrinking, forcing designers to search for more available power in less space.

SynQor is responding to these emerging trends and changing customer requirements. The 40A PowerQor provides the most usable power in a half brick format without the need for a heatsink. Designers who previously would have required the use of a 40A full brick can now remain in a half-brick footprint and save precious board space. By eliminating the heatsink and baseplate, the PowerQor converters provide an exceptionally low profile (0.4") to further reduce card pitch. In severe thermal environments the 40A PowerQor units can provide additional power where a derated 30A converter would fall short or become too hot.

The new PowerQor modules feature an expanded output voltage trim-up range of +20% to compensate for distribution resistive drops, which are more severe in low voltage, high current applications. The converters also use the industry standard pin-out to facilitate integration into existing designs.

The 40A PowerQor product line includes output voltages of 3.3V, 2.5V, 2.0V, 1.8V and 1.5V. All units draw power from a 48V nominal input (range: 35V to 75V). Full load efficiencies are 89% for the 3.3Vout unit, 87% for 2.5Vout, 85% for 2.0Vout, 84% for 1.8Vout and 82% for 1.5Vout.

The PowerQor line of DC-DC converters feature many practical control and protection features to facilitate system design. All PowerQor series products offer On/Off control with positive/negative logic, remote sense, output voltage trim, input under-voltage lockout, input over-voltage shutdown, output current limit, output over-voltage limit, and over-temperature protection.
