New dc-dc converters offer 90% efficiency

TDK-Lambda has introduced a new family of single and dual-output dc-dc converters that provide a broad range of inputs and outputs for a variety of industrial, telecom, and process control applications. Comprising the PXD30W Series, these converters feature six-sided shielded metal cases that reduce the radiated noise to meet EN55022 Level A specifications.

The PDX30W series offer a wide 4:1 input range of either 9 to 36 or 18 to 75 Vdc, which reduces the number of parts that need to be inventoried at the user's facility and also enhances the flexibility of the end system. Footprints for the devices are industry standard 2 x 1 x 0.4 in. Available output voltages include single outputs of 3.3, 5, 12, or 15 Vdc, and dual-outputs of +/-3.3, +/-5, +/-12, or +/-15 Vdc.

The devices boast efficiencies of up to 90% and MTBF in excess of 3.1 million hours, are safety-approved to UL/IEC/EN60950-1 specifications, and carry the CE Mark. Remote “On/Off” is a standard feature of all models and “Trim” is standard on all single-output units. For more information, contact TDK-Lambda Americas Inc., 3055 Del Sol Blvd., San Diego, CA 92154.
