DC/DC converter requires no heatsinking

27 June 2007 Power Electronics / Power Management

Providing designs engineers with a point-of-load device for a variety of applications, BI Technologies offers a fixed 5 V output DC/DC converter. Designated the MS2378, the 2 W converter is packaged in a hybrid SIP configuration and uses a ceramic base and hybrid technology which, according to the manufacturer, eliminates any heatsinking requirements.

The device features a fixed output voltage of 5 V (with a 3,3 V version also available) at up to 400 mA, and an input voltage range of 12 to 32 V d.c. Line regulation is 1% (measured at 16 to 32 V at 400 mA) with load regulation of 1% (at 100 mA to 400 mA). Operating temperature is -10 to +70°C. BI Technologies will also produce devices outside these specifications to meet customer requirements. It measures 25,4 mm long x 12,7 mm high x 5,7 mm thick, with typical lead spacing of 2,5 mm, and can be vertically or horizontally mounted.
