AC/DC switching power supply

The ECM100 single-output AC/DC switching power supply from XP Power is touted to be the world's most compact unit of its type. This device features a 4.5-by-2.5-inch footprint and a 1.2-inch height, delivering a power density of 7.4W/inch3. According to the press release, the compact size of the ECM100 has been achieved by minimizing component count and using just two heatsinkshalf the number found in most alternative designs. In addition, the design of the flyback converter combines continuous and discontinuous modes of operation to enable a much smaller transformer to be used.

The ECM100 has a earth leakage current of Outputs are from 3.3Vdc to 48Vdc and the power supplies have safety approvals for any voltage within this range, including custom-specified outputs. Input voltage is from 85Vac to 264Vac (170Vdc to 270Vdc) and efficiency is up to 87 percent.

Outputs are adjustable by 5 percent on 3.3V and 5V models, and by 10 percent on those with higher output voltages. Line and load regulation are 0.5 percent and 1 percent respectively and there is no minimum load requirement. Rated for operation between the 0 to 80C temperature range, the new power supply features over-temperature, over-voltage and overload protection. In addition, this product features Class I and Class II approvals, EN61000-3-2,-3 compliance, and Level B performance for conducted emissions.

Designed for industrial, medical and communications OEM applications, the ECM100 is priced at $52 each for 1,000 pieces.
