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.
APPLICATIONS
• Battery Operated Equipment
• Telecom
• Industry Control Systems
• Wireless Networks
• Measurement Equipment
