TDK Corporation announces the introduction of the GQA120 series of 120W industrial grade DC-DC converters. Four package types allow product performance to be optimized for the application.

The GQA120 series utilizes the industry standard quarter brick pin-out and has four packaging options. For convection cooled environments the flanged baseplate version is suitable for coldplate cooling and models with the non-flanged baseplate can be fitted with a standard quarter brick heat-sink. The cost optimized open-frame construction is suitable for applications with
airflow, or the encapsulated design is best suited for high temperature, harsh environments with minimal airflow. All models have a baseplate temperature rating of -40oC to +105oC. 5V, 12V, 15V, 24V, 28V and 48V nominal outputs are available and can be adjusted -10% / +10% using the trim function. The 5V to 28V models will operate with a 9 to 36Vdc input and the
91.5% efficient 48V output from 18 to 36Vdc. All models can withstand a 1 second surge of up to 50V. The GQA120 will automatically recover following an input under-voltage, output overvoltage, over-current or over-temperature condition.
Input to output isolation is 3,000Vdc for the flanged encapsulated models, 2,250Vdc for the encapsulated non-flanged and 1,500Vdc for the open frame construction. The series is safety certified to IEC/EN/UL 60950-1 with CE marking for the Low Voltage and RoHS2 Directives.
