The 3DPM0211-1 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 derating rules, the 3DPM0211-1 POL Converter is an ITAR Free product and features a SEL LET threshold of 80 Mev.cm2/mg and a TID of 50krad(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 voltages power supplis 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 in high speed modern ASICs, FPGAs and Memory devices.
TThe 20-A POL converter provides full protection against output short-circuit conditions. It also includes input under-voltage protection (UVP) and thermal shutdown circuitry, which disables operation when the internal temperature of the power module exceeds its specified thermal limit. This robust and efficient design makes it ideally suited for advanced space applications requiring high reliability and dependable power delivery.
Space satellite point of load supply: FPGA, CPLD, DSP, CPU core, and I/O voltages.
