The DSM/DWR series is available with three different input voltage ranges: 36-75V input (D48), 18-36V input Fully isolated, 1500Vdc guaranteed (D24) or 10-18V input (D12). These converters are fully isolated and capable of delivering any combina- 40 to +100C operating temperature tion of 5V and 3.3V output current up to a combined total of 15 Watts of output power. Input under and overvoltage shutdown Housed in 1 x 2 metal packages coated with electrically non-conductive nish, DSM/DWR convert- Output OVP, thermal shutdown ers 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 ltering, input overvoltage and undervoltage shutdown circuitry, output short- circuit and current-limiting protection, and thermal shutdown. All models provide trim capability and an on/off control function. Fully synchronous output recti cation provides high ef 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 speci ed for 40 to +100C operation. These devices meet IEC950, UL1950 and EN60950-1 safety standards.D48 models are CE marked (meets LVD requirements).

Tested from 250mA to 100% full load (other output at 250mA load). Nominal line voltage, no load/balanced full-power condition. Any combination of 5V/3.3V rated IOUT current, not to exceed 15 Watts of output power. (See derating graphs.) Ripple/Noise (R/N) measured over a 20MHz bandwidth. All models are speci ed with 0.47F ceramic in parallel with 100F tantalum output capacitors.
