PXG-M and PXD-M30 DC/DC Converters

TDK Corporation's 15 W to 20 W PXG-M and 30 W PXD-M30 board mount DC/DC converter series offer input to output isolation of 5,000 V_AC, allowing them to be used in multiple medical and industrial applications. With 4:1 input ranges of 9 V_DC to 36 V_DC and 18 V_DC to 75 V_DC, the two series are certified to IEC 60601-1 (medical) and IEC 62368-1 [ICT (information and communication technology) equipment].

The PXG-M and PXD-M30 series have industry-standard package sizes with overall dimensions of 40.6 mm x 25.4 mm x 10.2 mm (1.6" x 1.0” x 0.4”) and 50.8 mm x 25.4 mm x 10.2 mm (2.0" x 1.0" x 0.4”), respectively. Single outputs are available in 5 V, 12 V, 15 V, and 24 V and dual outputs are available in ±5 V, ±12 V, and ±15 V for 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. Overcurrent, overvoltage, and overtemperature protection is standard. Off-load input current consumption is just 12 mA 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 5,000 V_AC (2 x MOPP) and less than 2.5 μA 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 or EN 55032-A.
