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.
