SynQor Introduces Wide-Input, Point-of-Load DC-DC Converters

16Amps, 95% efficiency in standard SIP package

Boxborough, Mass SynQor, Inc. has launched a new line of non-isolated DC-DC converters with a wide input range from 3.0V to 5.5V. The NiQor series can deliver up to 16 amps of total output current in an industry standard single-in-line package (SIP). The new line of non-isolated, point-of-load converters represents SynQor抯 expanding product line for distributed power applications and intermediate bus architectures.

The NQ04 series modules accommodate standard input bus voltages of 3.3V and 5.0V while delivering 15 amps of current at fixed voltages of 0.9V, 1.0V, 1.2V, 1.5V, 1.8V, 2.5V and 3.3V outputs. SynQor also offers a wide trim module that delivers up to 16 amps and can be trimmed to any voltage from 0.75 to 3.6V with a single resistor to allow for maximum flexibility and reduced SKU count.

The modules employ synchronous rectification and a fixed switching frequency to achieve very high efficiencies up to 95%, allowing full power with no derating at ambient temperatures up to 70oC under natural convection. On board input and output filtering keeps input ripple currents and output noise to a minimum, eliminating the need to add expensive I/O capacitors. Employing the industry standard SIP package, the units measure 2.0 x 0.55 x 0.29, (50.8 x 14 x 7.4mm) and can be configured in either vertical or horizontal mounting orientations. SynQor plans to introduce a surface mount version of the modules in 2004.

The non-isolated NiQor series offer point-of-load power processing for a variety of low voltage core logic levels required for today抯 advanced DSPs and ASICs. Combined with SynQor抯 expanding product line of PowerQor isolated converters and BusQor dc transformers, power designers can implement a true Intermediate Bus Architecture (IBA). Supplying power to an array of different low voltage loads can be accomplished most economically with one point of isolation from an intermediate bus. The NiQor series then allows point-of-load power from the isolated high current bus for under $1/Amp.

The NiQor converters include a full complement of control and protection features such as on/off control, remote sense, input UVLO, over-current shutdown, output OVP, thermal shutdown, and industry standard output voltage trim.
