Hi Reliability, Ultra-Miniature, 0.2" ht.
Isolated DC-DC Converters
This series of unregulated DC-DC converters offer you a 0.200" tall package. 96
different models are available and all offer very low current consumption to operate in battery driven circuits.
Isolated, single and dual outputs will operate from -25º C to +70º C with no heat sink or derating required. Built-in
output capacitors and 4 convenient input voltages also help in simplifying your design, and with the addition of our
new DIP package, board layout and assembly is simplified.
