POL Converter


3D PLUS Radiation Tolerant Point-Of-Load DC/DC Converter provides high performances, high reliability, compact size and low weight for Space Applications.
From a 4.5V now available on almost every digital system, it provides a single output voltage adjustable with a very high efficiency. A very high speed control loop keeps the output voltage within regulation under the high transient load swings commonly found in high speed modern ASICs, FPGAs and Memory devices.
The PoL Converter is fully protected against output overload, input under-voltage and internal over heating. The external ON/OFF command and Soft Start function enable any power supply ON/OFF sequencing. Power Good signal is available for module survey and may be used for Power on Reset.
Input and output EMC filters are integrated to simplify module implementation directly on the digital board, and, to enable the maximum area and weight savings for the space applications boards’ designs.
The PoL Converter is offered with gull wing SMD package for high resistance SMT assembly and for withstanding harsh thermal and mechanical environments.
3D PLUS PoL Converters products can be used for the power supply of fast and low voltage digital electronics (FPGAs, DDR and DDR2 SDRAM Memories) and in a variety of distributed power system designs.
