0.5D14B_3UP Series
0.5W - Single Output DC-DC Converter - Fixed Input - Isolated & Unregulated
DC-DC Converter
The 0.5D14B_3UP series are miniature, isolated 0.25W DC/DC converters
in a SIP and DIP package.
0.5 Watt
Short circuit protection (SCP)
3KVDC Isolation
Power density up to 0.85W/cm3
Power sharing on dual output
Industry standard pinout
RoHS compliance
Temperature range:
-40°C ~ +105°C
They offer the ideal solution in many space critical applications for
board level power distribution. The internal SMD construction makes it
possible to offer a product with high performance at low cost. The
series offers smaller size, improved efficiency, lower output ripple noise
and 3KVDC isolation.
Efficiency up to 80%
Footprint from 1.17cm3

Note:
1. Operation under minimum load will not damage the converter; However, they
may not meet all specification listed, and that will reduce the life of product.
2. All specifications measured at Ta=25°C, humidity<75%, nominal input voltage
and rated output load unless otherwise specified.
