GE's Critical Power business today 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. These features provide exceptional power density in a single, flexible module. For more product details, visit www.dlynx.com.

The new UDXS1212 power module offers original equipment manufacturers (OEMs) a high-density solution by utilizing two 12-amp 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."

The UDXS1212's industry-standard PMBus interface and space-saving Tunable Loop technology deliver leading current density for a broad range of applications including data communications, telecommunications, storage, industrial, medical and military infrastructure equipment. 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 volts DC to 5.5 volts DC.;
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.;
Supports 12 amps at 1.2 volts up to 80 degrees Celsius without airflow.;
Interleaved 180 degrees out-of-phase to reduce input ripple when both outputs are operating.
