RGC Series 

300W, 9 to 53V Input Non-Isolated Ruggedized DC-DC Buck-Boost Converters 

http://product.tdk.com/en/power/rgc www.emea.lambda.tdk.com/rgc 

The rugged RGC non-isolated DC-DC step-up and step-down converters are encapsulated in a five-sided aluminum case and rated for up to 115°C operation. The modules have the industry standard 1/16th brick pin-out, are qualified to MIL-STD-810G (shock and vibration) and designed for fan-less, conduction cooled applications. The series accepts a wide input range to support multiple DC bus and battery voltages. Standard features include remote on/off, remote sense and output trim while a full feature adds power good, frequency synchronization and output current monitoring, making the modules a truly versatile board mount power solution. The wide output adjustment range allows one model to be used in multiple positions, assisting inventory and part number reduction.

## **Typical Application Circuit** 

## Recommendation 

1. Cin/Cout MLCC should be connected to the RGC module as close as possible in order to reject high frequency noise. 

2. Connect Vin(-) and Vout(-) to copper ground plane underneath the RGC module. 

3. TRIM resistor “Rup” should be connected to the RGC module as close as possible. 

4. SYNC must be connected to GND when not in use. 

5. External R-C filter should be present when using Current Monitor.
