The DAC2800D series of DC-DC converters provides the ruggedness reliability and features required to meet the advanced design challenges of today's hi-rel market. This has been accomplished while retaining a power density of 15 W/ in3 and 375 mW/gram of power/package performance. The use of advanced substrate and reflow soldering techniques during construction results in a rugged, cost-effective, and completely solderable package.
The DAC2800D series from M.S. Kennedy are dual‑output, fully regulated DC‑DC converters with high isolation (500 V) and operation from –55 °C to +125 °C. They use all‑ceramic capacitors, surface‑mount magnetics and a transformer‑isolated flyback topology at 400 kHz.
The datasheet provides absolute maximum ratings, electrical specifications such as a 50 V input range, up to 360 mA continuous output current, efficiency up to 65 %, and mechanical data including 14 g weight and a 0.925 in² footprint. Ordering information and pin functions for output adjustment, shutdown and fault monitoring are also included.
| Input voltage range | 50 Vdc |
|---|---|
| Output voltage options | +12 V or +15 V |
| Continuous output current | 360 mA (DAC2812D) / 288 mA (DAC2815D) |
| Isolation voltage | 500 V |
| Weight | 14 g |
| Operating temperature range | -65 °C to +125 °C |
The output voltage can be adjusted from 90 % to 110 % of nominal by using pin 4 (adjust/comp) with a potentiometer.
Remote shutdown is achieved by connecting pin 5 to an open‑collector logic output or a switch rated at 2.5 mA, 25 V.
The converters accept a maximum input voltage of 50 Vdc.
