ATA00A36S-L is a 3-watt isolated DC-DC converter designed for low-power applications in data communication, telecommunications, computer peripherals, industrial automation, and mobile battery-powered systems. The converter accepts an input voltage range of 18-75 VDC and delivers a regulated 5V output at 600 mA with 78% efficiency. It features ultra-compact SMD packaging (23.8 × 13.7 × 8.0 mm), 1500 VDC input-to-output isolation, and operates reliably across -40°C to +85°C. The device includes remote ON/OFF control, hiccup-mode short-circuit protection, and meets UL/cUL/IEC/EN 62368-1 safety standards with CE marking. Its wide 4:1 input range, low output noise (100 mV), and lead-free reflow compatibility make it ideal for space-constrained applications requiring high reliability and regulatory compliance.
