Vicor high-input quarter-brick modules fill mid-power space

Seven mid-power DC/DC converters from Vicor, additions to the company's quarter brick-sized Micro family of 300Vdc input modules for offline power systems, include two 50W models for 3.3Vdc and 5Vdc, and five 75W models (12-, 15-, 24-, 28- and 48Vdc) for industrial and process control, distributed power, medical, ATE, communications, defence and aerospace applications. "These mid-power Micros offer customers a cost-effective solution for applications that don't require the full power capability (100W to 150W) of the Micro module," said Bob Marchetti, manager of product marketing.

General features of the Micro modules include wide DC input (180Vdc to 375Vdc), regulation of ±0.5 per cent no-load to full-load, output programmable from 10 per cent to 110 per cent of nominal specified voltage, efficiency from 77 per cent to 88 per cent (higher-output voltage modules have higher efficiency), parallelable operation with n + m fault tolerance, and maximum operating temperature to 100°C at full load.

Pricing for the mid-power Micro modules, in 1,000 quantities, begins as low as Rs.32.14 (72 cents) per watt.
