3DPM0211

The 3DPM0211 PoL DC/DC Converter provides high-performances, high-reliability, compact size and low weight for space applications. Featuring specific radiation effect mitigationtechniques and utilising space design de-rating rules, the 3DPM0211 PoL Converter is an ITAR free product and features a SEL LET threshold of 80 MeV.cm²/mg and a TID of 50 Krad (Si). Based on a Buck topology, the PoL module uses a P Channel Power MOSFET/Schottky diode stage at 400 kHz switching frequency.

From a 5V now available on almost every digital system, the PoL module provides low voltage power supplies for most of today's digital designs. Its Output voltage is adjusted from 1.225V to 3.8V by an external resistor. A very high speed control loop keeps the output voltage within regulation under the high transient load swings commonly found a high speed modern ASICs, FPGAs and memory devices.

The PoL module 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 with only one additional component (resistor for output voltage adjustment).
