The SK01S/D series is a family of compact 1W dc/dc-converters with wide 2:1 input voltage ranges and tightly regulated output voltages.
They work with high efficiency over the full load range and come with a remote On/Off control input.
High efficiency to 82% allows operating temperatures up to +75°C without power derating. The very small footprint of these converters make
them an ideal solution for many space critical applications in communication equipment, instrumentation and many other battery operated
applications.

Specifications typical at Ta=+25℃, resistive load, nominal input voltage, rated output current unless otherwise noted.
We recommend to protect the converter by a slow blow fuse in the input supply line.
Other input and output voltage may be available, please contact factory.
That “natural convection” is about 20LFM but is not equal to still air (0 LFM).
Specifications are subject to change without notice.
