RGC Series Ruggedized Non-Isolated DC/DC Converters

TDK-Lambda RGC series of ruggedized non-isolated DC/DC converters are capable of operating from an input voltage of 9 V to 53 V. These step-up/step-down converters deliver output voltages that can be adjustable from 9.6 V to 48 V or 5 V to 28 V with output currents of up to 12.5 A.

With a 1/16th brick pinout and measuring 38.1 mm x 39.4 mm x 13.0 mm, the converters are encapsulated to provide shock and vibration performance to MIL-STD-810G. The five-sided aluminum case reduces radiated EMI and enables conduction cooling to a cold plate for fanless operation.

The RGC series comprises two voltage and current combinations to support operation from 12 V, 18 V, 24 V, 36 V, and 48 V power sources. The wide input and output voltage ranges can assist with inventory reduction programs with one part number covering multiple voltages. With efficiencies of up to 97%, power losses are minimized allowing the products to operate in harsh environments with a case temperature of -40°C to +115°C.

The basic feature models include an output voltage adjustment pin, negative logic remote on-off, remote sense, input undervoltage, overcurrent, and thermal protection. The full-feature models are equipped with a power good signal, current monitoring, and the ability to synchronize the operating frequency to minimize system noise. All models carry the CE and UKCA marks for the Low Voltage and RoHS directives and are designed to the IEC/UL/CSA/EN 62368-1 safety standards. Evaluation boards are available for quick and easy testing.
