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. |**Features**|**Benefits**| |---|---| |• Up to 300W in a 1/16th Brick-Pin-Out|• High Power Density, Less Board Area Needed| |• Encapsulated in a 5-sided Aluminum case|• Improves EMI| |• 115°C maximum case temperature|• Rugged deployment in harsh environment with high shock & vibration exposure| |• Efficiency - Up to 97%|• Longer Battery Life / Low Power Consumed| |• Wide Output Adjustment from 5 up to 48V|• One Part Supports Multiple System Voltages| |• Wide Input Range from 9 to 53V|• Can Operate from Different DC Input Source Voltages| |• Buck-Boost - maintains output regulation even when input varies|• Extends run times on battery-powered equipment| ## **Model Selector** ||Input|Output|Max|Max||Negative|| |---|---|---|---|---|---|---|---| |Model|Voltage

## **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.
