Description
The SD single series breaks new ground on several fronts.
First is their power density of up to 25 watts per cubic inch. The
second is the operating efficiency that can exceed 90%.
The outputs are 3.3 and 5 volts with 5 volt or 6-15.5 volt
inputs respectively. This makes these converters ideal for
logic powered 3.3 volt down conversion or battery operation
of the more traditional 5 volt logic powered systems.
Coupled with this is the very low output noise of typically
less than 60 mV peak to peak. The noise is also fully specified
for RMS value and if even these impressive noise figures
aren’t enough, our applications section shows a simple add
on circuit that can reduce the output noise to less than 20 mV
P-P.
The traditional flat package design has been stood on end
so that it takes up only 1 square inch of PCB area. No extra
heatsinking is required for most applications saving you
design time and valuable PCB space.
What all this means to you is a tighter, more compact
overall system. Full application information is provided to
make integrating this supply in your system a snap.
A remote ON/OFF function is included that places the
converter in a very low power state.
As with all CALEX converters the SD Single series is
covered by our 5 Year Warranty.
