Electronics CELThe 250 W rated TDK-Lambda i6A series of non-isolated DC-DC converters are capable of operating from an input voltage of 9 to 40 V, the step-down converter delivers an output voltage that can be adjustable from 3.3 to 24 V and output currents of up to 14 A.
The series is designed to be used in a wide range of applications including medical, communications, industrial and test and measurement equipment.
In a 1/16th brick form factor, measuring 33 x 22.9 x 12.7 mm, the converters can be used in conjunction with a single output 12 V or 24 V AC-DC power supply to generate additional regulated high current outputs, with or without battery back-up.
With efficiencies of up to 98%, power losses are minimized allowing the products to operate in harsh ambient temperatures of -40º to 125ºC even with low airflow requirements.
The need for external output capacitance is reduced due to an optimized dynamic voltage response, thus reducing board space requirements.
The basic feature models include an output voltage adjustment pin, positive or negative logic remote on-off, remote sense, input under-voltage, over-current and thermal protection.
Full feature models are equipped with a power good signal, output voltage sequencing and the ability to synchronize the operating frequency to minimize system noise. All models are certified to UL/CSA 60950-1, IEC/EN 60950-1 and carry the CE mark for the Low Voltage and RoHS2 Directives.
