The PXD20-12D12 is a 20W isolated DC-DC converter with a 2" x 1" footprint, designed for telecom and datacom applications. It accepts a 9 to 18VDC input and provides dual 12V outputs at up to 0.833A each, with ±1% voltage accuracy and 86% efficiency. The unit features six-sided shielding, reducing radiated noise, and supports remote on/off with negative logic. It operates over a temperature range of -40°C to +85°C, with a maximum case temperature of +100°C. The converter meets IEC/UL/CSA/EN 62368-1 and 60950-1 safety standards, carries CE marking, and complies with EN55022 Level A emissions and EN61000-4-2, -3, -4, -5, -6 immunity requirements. It measures 50.8 x 25.4 x 10.2 mm and weighs 27 g. Input surge withstand is 36V for 100ms. Isolation voltage is 1600VDC minimum, and MTBF is 1,791,000 hours per BELLCORE TR-NWT-000332. The part includes output trim and negative logic remote on/off as standard options.
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 10 to 60W 2" x 1" 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 48V) and dual output (±5V, ±12V or ±15V) models are available with a choice of positive or negative remote on/off and optional adjustment trim pin.
