PXD40/PXD60 Series DC/DC Converters

TDK-Lambda’s 40 W and 60 W rated PXD series of 2” x 1” DC/DC converters are capable of operating from a wide input voltage of 9 V_DC to 36 V_DC or 18 V_DC to 75 V_DC. 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 are comprised of 3.3 V_DC, 5 V_DC, 12 V_DC, 15 V_DC, 24 V_DC, and 48 V_DC single outputs, and ±12 V_DC, ±15 V_DC, and ±24 V_DC 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 as low as 3 mA 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 up to 93%, power losses are minimized allowing the products to operate with a case temperature of -40°C to +105°C. 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 1,600 V_DC.
