IR Introduces D Series of Low Power High Reliability Two Output DC-DC Converters for Satellite Power SystemsEL SEGUNDO, Calif. --(Business Wire)-- International Rectifier, IR® (NYSE: IRF), a world leader in power management technology, today announced the introduction of the D Series of low power radiation-tolerant two output DC-DC converters developed to meet the high reliability design needs of satellite power systems. The new D28xxD and D50xxxxP D Series of DC-DC converters offer extremely low output noise, guaranteed End-of-Life (EOL) output voltage drift with excellent output cross regulation. Each converter output is independently regulated with 5W maximum rated output power or 10W total output power. Available in two output configurations, the first configuration offers the traditional positive and negative output combination for analog and linear circuit loads. The second configuration features two positive outputs where each output may have the same or different voltages with each voltage as low as 1V and as high as 5V. This version is well suited to DSP, FPGA, DDR memory and other digital loads. Each converter output is independently regulated with 5W maximum rated output power or 10W total output power. Following IR's design standards, the D series are designed to meet MIL-STD-1547B and NASA's EEE-INST-002, the industry's de-rating standards for EEE components stress de-rating. "Developed using a proven design methodology, and featuring two outputs with excellent output cross regulation in one compact converter package, IR's D eries offers a highly reliable, high efficiency, small and lightweight solution for both analog and digital satellite system applications," said Tiva Bussarakons, Marketing Director, IR's HiRel Business Unit. The D Series DC-DC converters incorporate IR's proprietary PWM controller IC which integrates several performance enhancing circuitries to minimize overall component count and improve reliability. Linear post regulation based on proprietary design is used for both outputs for low noise and high audio rejection. With a low weight of < 55 grams, the new converters are characterized with total ionizing dose (TID) of greater than 50K Rad(Si), and single event effect (SEE) linear energy transfer (LET) of heavy ions greater than 40 MeV.cm2 /mg.
