TDK-LAMBDA AMERICAS RGA series 250W rated ruggedized non-isolated dc-dc converters are capable of operating from an input voltage of 9 to 40V or 9 to 53V. The step-down converter delivers output voltages that can be adjustable from 3.3 to 15V, 3.3 to 24V or 3.3 to 40V with output currents of up to 20A. Product series is designed to be used in harsh environment applications including robotics, AGVs (Automated Guided Vehicles), communications, COTS, industrial and portable battery-powered equipment. In a 1/16th brick form factor, measuring 35.6 x 25.6 x 13mm, units are encapsulated to provide a higher resistance to shock and vibration. The five-sided aluminum case reduces radiated EMI and enables conduction cooling to a cold-plate for fan-less operation.
