Dual 12-A PoL modules offers 30 percent reduction in board space
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 features provide exceptional power density in a single, flexible module.
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.
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.
The UDXS1212 POL modules have a broad input range of 4.5 V to 14.4 V and a precisely regulated output voltage from 0.51 VDC to 5.5 VDC. The 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. Single micro-sized module (20.3 mm by 11.4 mm) providing two 12-A outputs (132 W maximum) achieves a higher density versus two individual modules, saving valuable board space and reducing cost.
The module supports 12 A at 1.2 V up to 80 degrees Celsius without airflow and is interleaved 180 degrees out-of-phase to reduce input ripple when both outputs are operating.
Availability and Pricing
GE’s UDXS1212 POL modules are available in volume quantity, with pricing beginning at $14.89 at OEM volumes.
