Ruggedised 250W DC-DC converters offer conduction cooling and wide range inputs and outputs

Posted by Dulcie on September 22, 2022

TDK-Lambda’s RGA series of DC-DC buck (step-down, non-isolated) converters are specifically designed for harsh environments. The encapsulated aluminium case provides high resistance against shock and vibration. Five-sided shielding reduces radiated emissions enabling easier system compliance. Heat can be conducted to a cold-plate for fan-less operation.

The RGA models comprise of three voltage and current combinations to support operation from 12V, 18V, 24V, 36V and 48V power sources. The wide input ranges can assist inventory reduction programs, with one part number covering multiple nominal voltages. With efficiencies of up to 98%, power losses are minimised allowing the products to operate in harsh environments of -40°C to +110°C case temperatures. Typical applications include robotics, AGVs (Automated Guided Vehicles), communications, COTS (Commercial off-the-shelf), industrial and portable battery-powered equipment.
