Packaged industry-standard DIP's, Watt dual-output models DATEL's Series DC/DC converters fully regulated (±0.5% max. line, max. load), fully isolated (1000Vdc minimum), extremely efficient high guaranteed) building blocks providing true component-like flexibility convenience designers modern distributed power systems. Exploiting high-frequency (170-200kHz), flyback topologies contemporary, highly automated, assembly techniques, Model DC/DC's have enough room include input type) output filters within their package. Offering true "plug-andplay" convenience, these power converters require external components. They operate over full +75°C temperature range with output power derating. Output voltages either Volts. Input voltage ranges either 4.5-9V ("D5" models), 9-18V ("D12" models) ultra-wide 18-72V ("D48" models). Transient response time quick 200µsec. These extremely rugged modules fully encapsulated with thermally conductive potting compound. They moisture vibration resistant have established reputation outstanding MTBF. telecommunication, computer other EMIsensitive applications, these DIP-packaged DC/DC converters offer full EMI/EMC characterization data. Industry-standard pinouts make DATEL's Model DC/DC's ideal replacements other more costly, less reliable power converters. Similarly, they excellent choices design-ins systems demanding small size, cost high reliability.
