DSM-5/2.65-3.3/3-D12

Product Summary

For surface mount or through-hole applications requiring 15 Watts of power from 5V and 3.3V, DATEL
offers a new power sharing DC/DC converter capable of meeting your output current requirements. The
DSM/DWR series is available with three different input voltage ranges: 36-75V input (D48), 18-36V input
(D24) or 10-18V input (D12). These converters are fully isolated and capable of delivering any combination
of 5V and 3.3V output current up to a combined total of 15 Watts of output power.
Housed in 1" x 2" metal packages coated with electrically non-conductive fi nish, DSM/DWR converters
are regulated by a 3.3V control loop that provides load regulation of ±0.5% for 3.3V output and
±1.5% for 5V output.
All models include input fi ltering, input overvoltage and undervoltage shutdown circuitry, output shortcircuit
and current-limiting protection, and thermal shutdown. All models provide trim capability and an
on/off control function. Fully synchronous output rectifi cation provides high effi ciency (86%) and a stable
output under no-load conditions.
DSM/DWR power sharing modules offer low output ripple and noise performance, 1500 Vdc isolation
voltage, and are fully specifi ed for –40 to +100°C operation. These devices meet IEC950, UL1950 and
EN60950-1 safety standards. "D48" models are CE marked (meets LVD requirements).
