The AEE04F18-LS is a 13.2 W isolated DC-DC converter module designed for applications requiring reliable power conversion from 9–36 V input to 3.3 V output at 4 A. It features 1500 VDC input/output isolation, auto-restart short-circuit protection, and operates across a wide temperature range of -40°C to +71°C without derating. The converter delivers 84% efficiency at 12 V input, with output voltage tolerance of ±2.0%, line regulation of ±0.5%, and load regulation of ±1.0% for single output configurations. With a switching frequency of 300 kHz, output noise/ripple of 100 mV, and an encapsulated 1" × 2" package, the AEE04F18-LS is well-suited for industrial automation, instrumentation, test and measurement, and telecommunications systems where compact size and high isolation are essential.
