Cincon CQB75-300Sxx-CMFC(D) 50-75W DC-DC Converters

Cincon CQB75-300Sxx-CMFC(D) 50W to 75W Isolated DC-DC Converters offer 2:1 input at single output voltages of 5VDC, 12VDC, 15VDC, 24VDC, and 48VDC in an industry-standard quarter-brick size. The converters feature a wide input voltage range of 180VDC to 450VDC (300VDC nominal), 3000VAC reinforced isolation, efficiency up to 90%, and an operating temperature range of -40°C to +100°C. An optional heat sink is available to extend the full power range of the units.

The standard control functions include remote on/off (positive or negative) and ±20% (except for 5Vout) adjustable output voltage. With very low no-load power consumption (10mA), the Cincon CQB75-300Sxx-CMFC(D) 50W to 75W Isolated DC-DC Converters offer an ideal solution for energy-critical systems. The DC-DC converters are fully protected against input under-voltage lockout (UVLO), output overcurrent, output overvoltage, overtemperature, and continuous short circuit conditions.

The CQB75-300Sxx-CMFC(D) DC-DC Converters are highly suitable for distributed power architectures, telecommunications, servers, base stations, battery-operated equipment, and industrial applications. The devices are also compliant with EN55032 and EN45545.
