Rarely, Series low-power DC/DC converters been defined both cost DATEL's made-in-the-USA quality reliability. Series dual-output DC/DC's achieves this "best-of-both-worlds" status implementing proven circuit architecture (170-200kHz flyback design) full, SMT-on-pcb assembly (including surface-mount magnetics) that truly 100% automatically assembled. Packaged miniature 1.25" 0.8", DIP-like plastic packages (UL94V-0 rated) requiring external components, Series DC/DC's bring true component-like convenience designers today's distributed power systems. Output voltages Volts. Input voltage ranges 4.5-9V ("D5" models), 9-18V ("D12" models) ultra-wide 18-72V ("D48" models). DC/DC's fully isolated (1000Vdc guaranteed) include input type) output filters within their package. Output transient response quick 200µsec, while output ripple noise typically 75mVp-p. These rugged modules fully encapsulated with thermally conductive potting compound that contributes their outstanding moisture/vibration resistance impressive MTBF. They operate over full +75°C temperature range without derating. models have been thoroughly characterized (electrically, mechanically thermally), qualified (including HALT), EMI/EMC tested. Additionally, they certified UL1950, 22.2 IEC950. DATEL's Model DC/DC's excellent selections telecom/datacom, computer process-control applications demanding small size, cost high reliability. required, their design "flexibility" allows easy modification your application-specific requirements.
