The PXF40-48S12 is a 40W isolated DC-DC converter in a 2 x 2 inch (50.8 x 50.8 mm) board-mounted package, designed for industrial applications requiring a 36 to 75 Vdc input and a 12 Vdc output. It features a 6-sided shielded metal case for reduced radiated noise, remote on/off control with positive logic, and adjustable output voltage within ±10%. The converter meets IEC/UL/CSA/EN 62368-1 safety standards and operates with 89% efficiency at full load. It provides a maximum output current of 3.333 A, with ripple and noise limited to 75 mV pk-pk, and supports an external load capacitance of 2,360 µF. Overcurrent, overvoltage, and overtemperature protection are included with auto-recovery.
The DC-DC converter is a type of switching power supply that converts direct currents of buslines into direct currents that are needed for devices. TDK has a lineup of DC-DC converters under the TDK-Lambda brand for the industrial equipment market boasting high-reliability and long service life made possible with advanced circuit designing technology and high-density mounting technology. The lineup of DC-DC converters by TDK-Lambda also includes isolated and non-isolated types to meet various applications along with onboard, power module and unit types and a wide range of industry-standard sizes from brick-shaped to inch-sized.
Housed in a metal case for six sided shielding, these 40 to 60W 2" x 2" footprint converters cover the commonly used nominal input voltages of 12V, 24V or 48V with either 2:1 or 4:1 versions. Both single (3.3V to 15V), dual output (5V, 12V or 15V) or triple output (3.3V to 15V) models are available with remote on/off and adjustment trim pin (single/dual models).
