GE expands DualDLynx series with dual 6A POL modules



GE’s Critical Power business introduced its UDXS0606 and UVXS0606 non-isolated point-of-load (POL) power modules. These DC-DC board-mounted units extend GE’s DualDLynx* product family and offer up to 25% reduction in board space usage compared to previous and competing solutions.

The new dual 6-amp POL modules provide ultra-tight voltage regulation (+/- 1 percent), digital trim for power reduction, digital sequencing, over-temperature protection, output over-current protection (non-latching) and over-voltage protection. They also employ a PMBus interface for digital configuration, communication and control. These features provide exceptional power density in a single, flexible module. In addition, the module provides exceptional current derating over temperature, which enables the device to achieve full load (up to 90 degrees Celsius) without the need for external airflow for most application voltages.

The new UDXS0606 (digital) and UVXS0606 (analog) power modules utilize GE’s new Independent Power Train (IPT) feature. Each module has two independent outputs (dual on/off, trim, Tunable Loop*, and PowerGood), common input voltages and ground-terminal connections. Each output can be loaded to the maximum current capability. A single PMBus address can be used for two rails. The DualDLynx occupies up to 25 percent less board area over separate modules.

“GE’s latest embedded power innovation provides a significant size advantage making it an ideal offering for a wide range of vertical markets,” said Karim Wassef, general manager—embedded power products, GE’s Critical Power business. “In addition, the DualDLynx reduces total cost of ownership and can offer a time-to-market advantage over discrete solutions. These DualDLynx modules provide a cost reduction compared to two single-output modules and require less external input filtering.”

The DualDLynx’s industry-standard PMBus interface and space-saving Tunable Loop technology deliver exceptional current density for a broad range of applications including data communications, telecommunications, storage, industrial, medical and military infrastructure equipment.

Additional features and benefits include:
-Synchronization features and remote sensing make designing for strict noise and set point requirements easier and more accurate.
-PMBus digital interface, which supports a wide range of commands including on/off, trim, digital sequencing, margin, power good, rise time adjustment and input under-voltage lockout. The digital interface also offers output voltage, current and temperature measurement capabilities.
-Interleaved 180 degrees out-of-phase inputs reduce input ripple when both outputs are operating.
-Single, micro-size module (20.3 millimeters by 11.4 millimeters) with IPT achieves a higher density versus two individual modules, saving valuable board space and reducing cost.
-Supports dual 6-amp outputs at 1.2 volts and up to 90 degrees Celsius without airflow.
-Broad input range (4.5 volts to 14.4 volts) and precisely regulated output voltage (from 0.51 volts to 5.5 volts DC).
-Tunable Loop technology enables the user to optimize dynamic response to match the load with reduced output capacitance.
-Analog and digital options available.

GE will be showcasing the new DualDLynx along with its recently announced GigaDlynx* POL module, its SlimLynx units and other products in Hall A4, booth #260 at Electronica 2014 in Munich, Germany, Nov. 11-14. In addition, Wassef will be speaking on the topic, “Power Density: Designing in the Negative Space,” on Nov. 12 at 12:30 p.m.
