TDK Corporation announces the introduction of the 40W and 60W rated TDK-Lambda PXD series of 2”x1” DC-DC converters. Capable of operating from a wide input voltage of 9 to 36Vdc or 18 to 75Vdc, these converters have a copper case providing six-sided shielding for reduced EMI, simplifying system compliance. Industrial control, telecom/datacom, test, measurement, and battery-operated equipment are some of the many applications for the PXD.
The PXD40 and PXD60 converters comprise 3.3, 5, 12, 15, 24, and 48Vdc single outputs, and ±12, ±15, and ±24Vdc dual output voltages. Using the trim function, the single output models can be adjusted to compensate for voltage drops or to accommodate non-standard system voltages. The wide input ranges can assist with inventory reduction programs with one part number covering multiple nominal voltages.
All models have a negative logic remote on/off function as standard, which can be used to reduce the input current to a low 3mA to prolong battery life for portable equipment in standby mode. No minimum loading is required, and the converters are protected against output-overvoltage, overcurrent, and overtemperature conditions.
With efficiencies of up to 93%, power losses are minimized allowing the products to operate with a case temperature of -40oC to +105oC. Output power derating can be reduced with the use of optional heatsinks and/or system airflow.
All models carry the CE and UKCA marks for the Low Voltage and RoHS Directives and are certified to the IEC/UL/CSA/EN 62368-1 safety standards. The series has an input-to-output and input-to-case isolation of 1,600Vdc.
