This 30-W CCG30G series of dc-dc converters operates over a 4:1 input range. The converters are enclosed in 1- by 1-in six-sided shielded metal cases. The series is available with 3.3-, 5-, 12- or 15-V outputs and can operate from either a 9- to 36-Vdc or 18- to 76-Vdc input. This range helps to reduce inventory as the converters can operate from either 12- and 24-V or 24- and 48-V nominal inputs without the need to stock two parts. With operating efficiencies of up to 91%, the series operates in ambient temperatures from -40 to 85 °C.
