D5 Models .....................7 Volts
D12 Models ....................15 Volts
Input Reverse-Polarity Protection ..........None
Input/Output Overvoltage Protection ........None
Output Current........Current limited. Devices can
                       .......withstand a sustained output
                       ........short circuit without damage.

These are stress ratings. Exposure of devices to any of these conditions may adversely affect long-term reliability. Proper operation under conditions other than those listed in the Performance/Functional Specifi cations Table is not implied.

As supply voltages trend lower and load currents increase, centralized power becomes more impractical. The tight accuracy, low noise and quick transient response demanded by today's low voltage CPU's, ASIC's and DSP's make power processing at the point of use the only viable solution. The UNR-1.8-D5 18-33W series provides a complete line of non-isolated DC/DC converters to satisfy this requirement. With input voltages of 5V (-D5 models) and 12V (-D12 models) these converters offer standard output voltages of 1.8, 2.5 and 3.3 Volts and up to 10 Amps of output current in through-hole 1" x 2" metal cases.

With on/off control as a standard feature, these non-isolated converters UNR-1.8-D5 exploit full synchronous rectifi cation, and 100% automated assembly to deliver high effi - ciencies (to 91%) and low noise at low cost.

These versatile DC/DC's UNR-1.8-D5 are fully line and load regulated. They feature quick transient response (50sec), user-optional on/off control (for power sequencing), and output overcurrent detection and shutdown ("hiccup" technique with autorecovery). Their impressive guaranteed effi ciencies enable them to deliver fully rated output power from +40/50/60°C (ambient) without supplemental cooling.If your high current requirements have made the use of ineffi cient linear regulators impractical, take a look at one of DATEL's switching buck regulators. Their high effi ciency, ease-of-use, long-term reliability, and overall cost effectiveness will impress you. Safety agency approvals and EMC characterizations are currently in progress.
