GE Extends DLynx Series with New Dual 12-A Digital POL Modules

December 18, 2013 by Jeff Shepard

GE's Critical Power business has introduced its UDXS1212 non-isolated point of load (POL) dc-dc board-mounted power module, offering an industry-leading 30 percent reduction in board space over previous and competing solutions. The new DLynx Series power modules include GE's PMBus™ interface for digital configuration, communication and control, as well as adaptive voltage scaling for power reduction. The UDXS1212's industry-standard PMBus interface and space-saving Tunable Loop™ technology are suited for a broad range of applications including data communications, telecommunications, storage, industrial, medical and military infrastructure equipment.

The new UDXS1212 power module offers original equipment manufacturers (OEMs) a high-density solution by utilizing two 12-A parts in a single module instead of two individual modules. This greatly reduces the amount of board space required for installation of the module. In addition, the module provides exceptional current de-rating over temperature, which enables the device to achieve full load (up to 85 degrees Celsius) without external airflow for most application voltages.

“GE’s latest innovation provides a time-to-market and ease-of-use advantage over discrete solutions,” said Karim Wassef, general manager—embedded power products, GE’s Critical Power business. “In addition, the UDXS1212’s innovative integration techniques provide a significant size advantage, making it an ideal offering for a wide range of vertical markets.”

Additional features and benefits of GE’s UDXS1212 POL modules include: Broad input range of 4.5 volts to 14.4 volts and a precisely regulated output voltage from 0.51 to 5.5 Vdc. PMBus digital interface supports a wide range of commands including on/off, trim, margin, power good, rise time adjustment and input under voltage lockout. Digital interface also offers output voltage, current and temperature measurement capabilities. Tunable Loop technology enables the user to optimize dynamic response to match the load with reduced output capacitance. New synchronization features and remote sensing make designing for strict noise and set point requirements easier and more accurate.

Single micro-sized module (20.3 millimeters by 11.4 millimeters) providing two 12-amp outputs (132 watts maximum) achieves a higher density versus two individual modules, saving valuable board space and reducing cost. These units support 12A at 1.2Vdc up to 80 degrees Celsius without airflow. The dual outputs are interleaved 180 degrees out-of-phase to reduce input ripple when both outputs are operating. GE’s UDXS1212 POL modules are available in volume quantity, with pricing beginning at $14.89 at OEM volumes.
