REMOTELY CONFIGURABLE POL CONVERTER

ARTESYN'S NEW SIL15E-12M NON-ISOLATED POINT-OF-LOAD (POL) CONVERTER WITH INTEGRATED I²C BUS INTERFACE PROVIDES OPEN-ARCHITECTURE CONTROL FLEXIBILITY.



All programmable output control functions, including the precision setting of output voltage and margining, feature high-accuracy auto-compensation. The converters simplify PCB design qualification and production tests thanks to an active DC output control function, for a significantly more precise output voltage during normal operation and when voltage margining.

Due to an input voltage range of 10V to 14V and the exceptionally wide 0.8V to 3.36V output range, the SIL15E-12M POL converter enables a large number of different device supply requirements to be satisfied with just one model!

The converter uses a synchronous buck regulator topology with precision synchronous rectification control, and can generate up to 15A with an extremely high efficiency of 92% at full load.

Each converter is supplied pre-programmed to standard default values stored in non-volatile memory, and only requires additional programming by the user if a change in an operational function is desired.
  During product development, designers can program various functions of the converter to check board operation before locking in final parameters for production, thus reducing both development time and risk.

For example, designers could alter the converter's output voltage to overcome small distribution losses, to change voltage margining limits, or to examine the effect of switching the active DC output control function off. The converters are supplied with standard (default) ±5% margin limits and with the output control function on. The latter uses advanced techniques to maintain the output set-point very accurately over time and under different temperature and load conditions typically within ±0.75%.

Programming the POL converters on a board under development is simply a case of connecting its I²C bus connector via a USB cable to a standard PC running a Windows™ based configuration GUI (graphical user interface).

SIL15E-12M converters can be controlled independently or up to eight can be addressed simultaneously. The configuration software employs an intuitive, simple to use interface to minimize system prototype development time.
ARTESYN's SIL15E-12M POL converters accommodate a wide operational temperature range of -40°C to +85°C ambient, and are expressly designed as high reliability products with an MTBF (mean time between failure) in excess of 3.5 million hours (in accordance with Telcordia SR-332).

The converters feature remote sense and remote on/off functions, have no minimum load requirement, and are comprehensively protected against overtemperature and short-circuit conditions. They carry a full set of international safety approvals, including EN60950 (TÜV Product Service) and UL60950.

If you would like to familiarize yourself with these highly advanced POL converters, the test kit is available from CODICO. This evaluation set comprises two SIL15E-12M POL converters mounted on a PCB with an I²C bus connector, a USB cable to connect the board to a PC, a CD-ROM containing the configuration software and installation instructions, and a printed copy of the user guide.
