TDK Corporation recently announced the introduction of the 15 to 20W PXG-M and 30W PXD-M30 board mount DC-DC converter series. With 4:1 input ranges of 9 to 36Vdc and 18 to 75Vdc, the two series are certified to IEC 60601-1 (medical) and IEC 62368-1 (ICT – Information and Communication Technology equipment). The input to output isolation is 5,000Vac allowing them to be used in multiple medical and industrial applications.

The PXG-M and PXD-M30 series have industry standard package sizes, with overall dimensions of 40.6 x 25.4 x 10.2 mm (1.6 x 1 x 0.4”) and 50.8 x 25.4 x 10.2 mm (2 x 1 x 0.4”) respectively. 5V, 12V, 15V and 24V single and +/-5V, +/-12V and +/-15V dual outputs are available in all three power levels. The single output models have an output adjustment function using a trim pin.

The units will operate with convection cooling in ambient temperatures of -40°C to +105°C. Derating at high temperatures may be required, which can be minimized with the use of external airflow. Over-current, over-voltage and over-temperature protection is standard. Off-load input current consumption is just 12mA or less, allowing battery powered equipment to remain functional longer during periods of non-operation. Positive or negative logic remote on-off is optional.

The two series have an input to output isolation of 5,000Vac (2 x MOPPs) and less than 2.5μA touch current. Safety certification includes IEC/EN 60601-1, ANSI/AAMI ES 60601-1 and IEC/EN/UL/CSA 62368-1 with CE marking for the Low Voltage and RoHS Directives. No external EMI filtering is required for compliance to EN 55011-A, EN 55032-A.
