Non-isolated Wide-Range DC-DC Converters with Negative Outputs
TDK Corporation announces the introduction of the 75W rated TDK-Lambda i6AN series of negative output non-isolated dc-dc converters. Capable of operating from an input voltage of +9- to +40-Vdc, the step-down converter delivers an output voltage that can be adjustable from -3.3 to -30-Vdc and output currents of up to 8A. 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 12.7mm, the converters can be used in conjunction with a single output 12-, 24- or 36-Vout ac-dc power supply to generate additional regulated high-current outputs, with or without battery back-up.
With efficiencies of up to 94%, power losses are minimized allowing the products to operate in harsh ambient temperatures of -40 to +125 degrees C 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 models include an output voltage adjustment pin, positive or negative logic remote on-off, remote sense, input under-voltage, over-current and thermal protection. 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.
