Module DC-DC 1-OUT 3.3V 8A 40W 6-Pin Case C4

The newest products in the flagship A-Series are the UWR, 26-40 Watt isolated singles. Housed in standard 2" x 2" metal packages (which have traditionally carried 15-20 Watt devices), these power converters supply up to 9 Amps @ 3.3V or 8 Amps at 5V. They exemplify the relentless drive to bring designers more power/current, in standard packages/pinouts, without compromising reliability or resorting to thermal specmanship. Input voltage ranges are 10-18V (“D12” models), 18- 36V (“D24” models) or 36-75V (“D48”) models.Employing an advanced, fully synchronous, high-frequency (300-360kHz) forward topology, UWR 26-40W singles attain 88-90% efficiencies enabling full-power operation to ambient temperatures as high as +55°C without supplemental air flow. Assembled using fully automated, SMT-on-pcb techniques, these DC/DC’s additionally provide low noise (75mVp-p), high accuracy (±1%), tight line/load regulation (±0.5%), quick step response (200µsec), and stable no-load operation.All models feature input pi filters, input undervoltage and overvoltage shutdown, output overvoltage protection, current limiting, short-circuit protection, and thermal shutdown. Each model has a VOUT trim pin as well as an on/off control function that may be ordered with either positive or negative logic. These devices are fully isolated (1500Vdc) and satisfy UL/EN/IEC60950-1 safety requirements. “D48” models (36-75V inputs) are CE marked.
