With a typical line and load regulation of 0.2%Emerson Network Power's Astec AIF-300Vin full-brick DC/DC converters, which include a microprocessor with I?C interface and memory for advanced control and monitoring functionality, deliver up to 600W for demanding military, industrial, and test-and-measurement applications. The single-output converters, six versions in all, provide 1.8-, 3.3-, 5-, 12-, 15- or 24V at rated power from a 250V to 400V input.

Features include a typical line and load regulation of 0.2 percent, ripple and noise of 100mVpp (below 5V, 2 percent of the output at 5V and above), and operating efficiency of 90 percent at 5V. Operational features include current sharing, enable (positive and negative option), output voltage adjust, clock-in (for synchronization in parallel application), and monitoring of temperature and output current. The AIF's internal microprocessor, with I?C interface and EEPROM for storing system data, optimizes control and minimizes external connections. All models provide over-voltage, over-current, and over-temperature protection. The converters are rated for operation over -40C to 100C (case temperature). The series meets all major international performance and safety standards including those from UL, cUL, TUV and CE.

A preliminary datasheet is available online. The bricks are priced from $220 each in OEM quantities. The 1.8-, 3.3- and 5V models are already available, while the 12-, 15- and 24V output models will be available this month (July 2005).
