With an input voltage of 9 to 53 volts, the step-up/step down converters deliver adjustable output voltages from 9.6 to 48 volts or 5 to 28 volts.

SAN DIEGO – TDK-Lambda Americas Inc. in San Diego is introducing the 300-Watt TDK-Lambda RGC series of ruggedized non-isolated DC-DC converters for use in harsh-environment applications such as robotics, communications, industrial, and portable battery-powered equipment.

Operating from an input voltage of 9 to 53 volts, the step-up/step down converters deliver output voltages that can be adjustable from 9.6 to 48 volts or 5 to 28 volts with output currents of as much as 12.5 amps.

With a 1/16th brick pinout and measuring 38.1 by 39.4 by 13 millimeters, the DC-DC converters are encapsulated to provide shock and vibration performance to MIL-STD-810G. The five-sided aluminum case reduces radiated electromagnetic interference and enables conduction cooling to a cold-plate for fanless operation.

The RGC series of power supplies comprises of two voltage and current combinations to support operation from 12-, 18-, 24-, 36-, and 48-volt power sources. These devices have efficiencies to 97 percent, and operate in temperatures from -40 to 115 degrees Celsius.

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. The full-feature models have 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 mark for the low-voltage and RoHS directives and are designed to the IEC/UL/CSA/EN 62368-1 safety standards. Evaluation boards are available.
