ATA03H36-L is a 10-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 24 VDC output at 416 mA with 88% efficiency. It features I/O isolation of 1500 VDC, ultra-wide 4:1 input range, and operates reliably across -40°C to +80°C. The device is housed in an ultra-compact mini dual-in-line package measuring 23.8 × 13.7 × 8.0 mm for through-hole mounting, with output voltage tolerance of ±2.0%, line regulation of 0.8%, and load regulation of 1.0%. Safety approvals include UL/cUL/IEC/EN 62368-1 (60950-1) certification and CE marking, making it suitable for mission-critical applications requiring high reliability and compact form factor.
