Cincon CQB75-300S Isolated DC-DC Converters offer efficiency up to 90% and 75W output power at a single-output voltage range of 5V to 48V. The CQB75-300 series features an optional heat sink to extend the full power range of the unit. The DC-DC converters are fully protected against input undervoltage lockout (UVLO), output overcurrent, output overvoltage, overtemperature, and continuous short-circuit conditions. Cincon CQB75-300S DC-DC converters offer a fixed switching frequency and can operate up to an altitude of 3000m. These converters operate within a -40°C to +105°C temperature range and 180V to 450V supply voltage range. Typical applications include distributed power architectures, telecommunications, servers, base stations, battery-operated equipment, and industrial.
