18:1 Input Range DC-DC Converters Deliver 20 WattsDecember 07, 2019 by Paul Shepard
With Cincon's continued focus on the development of wide input range dc-dc converters, the company has introduced EC7BW18 Series. With a ultra-wide 8.5- to 160-Vdc (18:1) input range, these dc-dc converters provide 20 Watts of output power in a 2"×1"×0.4" package, with output options of 5-, 12-, 15-, ±12-, ±15-, and ±24-Vdc.
Although the EC7BW18 Series was primary design for all common railway applications, it is also suitable for other markets such as industrial, telecommunications, battery operated equipment, and distributed power architectures.
It has a very low no load power consumption requirement of 5- to 8-mA. Efficiency can go as high as 90%, allowing case operating temperature range of -40°C to 105°C.
Other features include remote on/off (positive or negative), and -20 to +15% adjustable output voltage. Safety approved for UL62368-1 / IEC62368-1. Compliant with EN50155 (EN61373), EN45545-2, and EN50121-3-2 requirements for the essential railway market needs (need external circuits).
Fully protected against input UVLO (under voltage lock out), output over-current, output over-voltage and over-temperature and continuous short circuit conditions, and offers isolation up to 3000Vac.
