Power Supplies 400 to 750W ruggedised buck DC-DC converters offer conduction cooling with a wide range of inputs and outputs

TDK Corporation (TSE:6762) announces the introduction of the 400 to 750W rated RGB series of ruggedised non-isolated DC-DC converters from TDK-Lambda. Operating from input voltages of 9 to 18V, 18 to 32V or 18 to 60V,  these buck step-down converters can deliver output voltages adjustable from 0.8 to 8V or 3.3 to 24V with output currents of up to 60A (depending on the power level). The series is designed to be used in harsh environment applications including medical, automated guided vehicles (AGV), industrial mobile robots (IMR), drones, commercial off-the-shelf (COTS), industrial, test, measurement, and battery-powered equipment.

Efficiencies of up to 98.5% allow the product to deliver high usable power in demanding thermal environments with case temperatures of -40^oC to +115^oC, while providing a longer battery life. With a 1/16th brick pinout and measuring 38.1 x 49.5 x 13.0mm (WxLxH), the converters are encapsulated to provide shock and vibration performance to MIL-STD-810G. The five-sided aluminium case reduces radiated EMI and enables conduction cooling to a cold-plate for fanless operation.

The basic feature models include an output voltage adjustment pin, negative logic remote on-off, remote sense, input under-voltage, over-current and thermal protection. An optional adjustable current limit is also available to reduce stress on the input source, converter, and load in the event of an overload.

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.
