TT electronics BI Technologies Electronic Components Division has developed a fixed output DC/DC converter with a wide input voltage range. The 831 series DC/DC converter is packaged in a 1-by-0.5-by-0.225-inch hybrid SIP configuration, and can also be vertically or horizontally mounted.

According to Mike Ochoa-Hougan, hybrid product manager for BI Technologies Electronic Components Division, the converter uses a ceramic base and hybrid technology that aims to eliminate external heat sink requirements. "All the device requires is two external capacitors," said Ochoa-Hougan.

The DC/DC converters are suited for commercial applications with a need for a point-of-load source of low-voltage power for control circuitry.

The 2W devices feature a fixed output voltage of 5V (3.3V available) at up to 400mA, and an input voltage range of 12Vdc to 32Vdc. Line regulation is 1 percent (measured at 16V to 32V at 400mA) with load regulation of 1 percent (at 100mA to 400mA). Operating temperature is 10C to 70C. BI Technologies said it will also produce devices outside these specifications.

Typical pricing for the 831 series converters is approximately $4 in medium range volumes, with lead times from stock to 8 weeks.
