PDQ DC-DC Converters

CUI Inc PDQ DC-DC Converters are ideal replacements for the larger 1” x 2” modules. These industry-standard 1" x 1" converters are available in an isolated output 10W to 30W in surface-mount or DIP options. The PDQ series features a 4:1 input range, efficiencies up to 91%, and a wide operating temperature range of -40°C to +105°C. Applications include convection-cooled equipment including microcontrollers, datacom, telecom, remote sensor systems, and portable electronics.
