TDK-Lambda’s RGC series of DC-DC buck-boost (step-up/down, non-isolated) converters are specifically designed for harsh environments. The converters are encapsulated in an aluminium case providing resistance against shock and vibration. Five-sided shielding reduces radiated emissions enabling easier system compliance. The RGC can be mounted to a cold-plate for conduction cooling, requiring no external forced air.

The RGC models accept a 9 to 53Vdc input to support operation from 12V, 18V, 24V, 36V and 48V power sources. Two output voltage ranges are available. The 8A output model has an output voltage adjustment of 9.6 to 48V and the 12A model 5 to 28V. The wide input and output ranges can assist with inventory reduction programs with one part number covering multiple nominal voltages. 

With efficiencies of up to 97%, power losses are minimized allowing the products to operate in harsh environments of -40oC to +115oC case temperatures. Standard features include remote on/off, remote sense and output trim, while the full feature version adds power good, frequency synchronization and output current monitoring
