Wide range dc-dc converters provide negative outputs
TDK Corporation’s 75W rated TDK-Lambda i6AN series of negative output 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 -30V 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. With efficiencies of up to 94%, power losses are minimized allowing the products to operate in harsh ambient temperatures of -40 to 125 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.
