The S5 Family of high efficiency non-isolated DC/DC converters offer power levels of up to 25 Watt, while also providing ultra-wide input voltage range for 3.3Vin and 5Vin, as well, as 12Vin. These
converters provide versatility without sacrificing the board space. All models feature an input filter and regulated outputs. The open-frame construction facilitates maximum power delivered with the
highest efficiency of up to 92%. All converters combine creative design practices with highly derated power devices to achieve very high reliability, high performance and low cost solution to
systems designers.

Measured From High Line to Low Line, Vo, set = 3.3Vdc
Measured From Full Load to Zero Load, Vo, set = 3.3Vdc
The output noise is measured with 10uf tantalum capacitor
and 1uf ceramic capacitor across output.
To reduce the input ripple voltage, parallel the Input Terminals
with 47uF Capacitor and 10uF Ceramic
