The 3DPM0024-3 POL Converter provides high performances, high reliability, compact size and low weight for Space Applications.
Featuring specific radiation effect mitigation techniques and utilizing space design de-rating rules, the 3DPM0024-3 POL Converter is an ITAR Free product and features a SEL/SEE LETth 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 and Schottky Diode stage at 400 kHz switching frequency.
From a 5V now available on almost every digital system, the POL converter provides low voltages power supplies for most of today's digital designs. Its Ooutput voltage is adjusted form 1.225V to 4V by an external resistor. A very high speed control loop keeps the output voltage within regulation under the high transient load swings commonly found in Converter Mhigh 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). More information
