DESCRIPTION
The DCHAA series of DC/DC power converters provides up to 6 Watts of continuous output
power in a 1.25” x 0.80” x 0.50” 24-pin DIP package. This series consists of single and dual output
models with 2:1 input voltage ranges of 9~18VDC, 18~36VDC, and 36~75VDC. Some features
include high efficiency up to 85%, 4000VACrms I/O isolation, -40°C to +85°C operating
temperature range, and no minimum load requirement. The DCHAA series is RoHS and UL94V-0
compliant. These converters are best suited for use in battery operated equipment,
measurement equipment, telecom, wireless networks, industry control systems, and anywhere
where isolated and compact size are required.
