SynQor Introduces 12V input, Point-of-Load DC-DC Converters
Available in SIP and Lead-Free Surface Mount packaging
Boxborough, Mass – SynQor, Inc. has announced
the release of a series of 16A non-isolated DC-DC converters with a 12V input.
The NQ12 modules, part of the NiQor™ family, are available in both an
industry standard SIP (single-in-line packaging) and lead-free surface
mount (SMT) form factor. The new point-of-load converters offer fast transient
response capability, 95% efficiency and power densities up to 400W/in3.
The NQ12 series modules accommodate a wide 12V +20% input bus (9.6V to 14.4V) while delivering 16 amps of current at fixed voltages of 0.9V, 1.0V, 1.2V, 1.5V, 1.8V, 2.0V, 2.5V, 3.3V and 5.0V outputs. SynQor also offers a programmable version that can be trimmed to any voltage from 0.75 to 5.5V with a single resistor to allow for maximum flexibility and reduced parts count.
The modules employ on board input and output filtering to keep input ripple currents and output noise to a minimum, eliminating the need to add expensive I/O capacitors. The converters are designed primarily for use in intermediate bus architectures (IBA), in which the POL modules convert power from an intermediate bus converter or standard isolated brick to a low voltage output required by the load. The NQ12 modules use a synchronous buck regulator topology and a fixed switching frequency to achieve very high efficiencies up to 95%. The superior thermal performance allows full power with no derating in a typical application at ambient temperatures up to 70°C under natural convection.
Modules are available in the industry standard SIP package, measuring 2.0” x 0.55” x 0.29”, (50.8 x 14 x 7.3mm) with both vertical and horizontal mounting orientations or in a surface mount package, measuring 1.3” x 0.53” x 0.29”, (33.0 x 13.5 x 7.3mm) with standard tape and reel options. The SMT modules use a lead-free solder and meet the requirements of Lead-Free 2 while accommodating a maximum reflow temperature of 260°C for 90 seconds.
The NiQor converters include a full complement of control and protection features such as remote on/off (positive/open), remote sense, standard voltage trim, input UVLO, over-current shutdown, output OVP, and thermal shutdown. The units have no minimum load requirement and carry relevant international safety approvals, including EN60950 and UL/cUL1950.
Sample and production quantities of the NQ12 SIP and SMT converters are available immediately with a 4-6 week lead-time.
