The ATA03F18-L is a 10-watt isolated DC-DC converter from Advanced Energy's Artesyn ATA series, designed for low-power applications in data communication, telecommunications, industrial automation, and mobile battery-powered systems. It features a 9-36 VDC input range with 3.3V output at 2700 mA, delivering 8.9 W of power with 80% efficiency. The module provides 1500 VDC I/O isolation, operates across -40°C to +80°C, and includes hiccup-mode overload and short-circuit protection with a switching frequency of 370 kHz. Housed in an ultra-compact mini dual-in-line package measuring 23.8 × 13.7 × 8.0 mm for through-hole mounting, it meets UL/cUL/IEC/EN 62368-1 safety standards and includes a three-year warranty. This converter is ideal for applications requiring reliable isolated power conversion in space-constrained environments with wide input voltage tolerance.
