The AVD75B-48S05-6L is a 75 Watt 1/16 brick isolated DC/DC converter designed for telecommunications equipment with a 36 to 75 VDC input range and regulated 5 V output capable of delivering 15 A. The converter features ultra-high efficiency up to 91.5% at full load, low output ripple and noise of 40 mV peak-to-peak typical, and operates across an ambient temperature range of -40°C to +85°C. It employs fixed frequency switching at 350 kHz to minimize external EMI filtering requirements, includes remote sense and trim functionality for output voltage adjustment (80% to 110%), and offers TTL-compatible enable control with auto-restart overvoltage protection at 130% of nominal output. The open-frame construction with optional baseplate provides flexibility for air or contact cooling, making it ideal for telecommunications, data center, and industrial power distribution applications requiring high reliability and compact form factor.
