Highly Regulated
Hi Reliability
Isolated
Ultraminiature DC-DC Converters
Low Profile .5" x 1" x .3" ht. up to 1 Watt
No Heat Sink or Electrical Derating Required
This series of encapsulated converters come in 60 different models. The highly regulated output is
isolated from the input. The units will operate over the temperature range of -25掳 C to +70掳 C. No heat
sink is required. These units are excellent for applications where the input voltage varies 卤10% and the
output must be held to 卤0.1% single/and 卤0.2% dual. The output voltage is maintained to within 0.2%
from no load to full load for single and 0.4% for dual.
