TDK-Lambda News

40W and 60W 2” x 1” DC-DC converters have a 4:1 input range and six-sided shielding

Posted : 08 Jun 2022

TDK Corporation (TSE 6762) announces the introduction of the TDK-Lambda brand PXD40 and PXD60 series of 40 and 60W DC-DC converters. Packaged in the industry-standard 2” x 1” footprint, the units can operate over a wide 4:1 input range, accepting either a 9 to 36Vdc or 18 to 75Vdc input. Operation from 12V and 24V or 24V and 48V supply voltages reduces inventory carrying costs and improves part availability. Six-sided shielding reduces radiated emissions and simplifies system compliance. Applications for the converters include industrial control, telecom/datacom and test & measurement equipment.

These latest PXD models are available with single outputs of 3.3, 5, 12, 15, 24 and 48V, or ±12, ±15 and ±24V dual output voltages. Single output models can be adjusted using the trim function by ±10% (-10 / +20% for 15 and 24V outputs). All models have a remote on/off function (positive or negative logic) and are protected against output-overvoltage, overcurrent and overtemperature conditions. No minimum loading is required.

Measuring 2” x 1” x 0.4” (50.8 x 25.4 x 10.2mm), the units will operate in case temperatures of -40°C to +105°C. Derating at high temperatures is dependent on the airflow and available heat sinking. The PXD40 and PXD60 products can also be supplied with an optional heatsink fitted.

Safety certification includes IEC/UL/EN62368-1 with CE and UKCA marking to the Low Voltage and RoHS Directives. The series has an input to output and input to case isolation of 1,600Vdc.
