The PXD20-48D12 is a 20W DC-DC converter with a 2" x 1" footprint, designed for point-of-load applications in telecom and datacom systems. It accepts a 36 to 75VDC input and provides a dual output of ±12V at up to 0.833A per rail. The converter features six-sided shielding, a 300kHz switching frequency, and includes remote on/off control with negative logic. It complies with IEC/UL/CSA/EN 62368-1 and EN55022 Level A emissions standards. Operating temperature ranges from -40°C to +85°C, with a maximum case temperature of +100°C. The isolation voltage is 1600VDC minimum, and the dimensions are 50.8 x 25.4 x 10.2mm. Ripple and noise are specified at 100mV for dual outputs. The part includes overcurrent and overvoltage protection with hiccup-mode recovery and meets MIL-STD-810D for thermal shock. Weight is 27g, with a 3-year warranty.
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.
