The converter’s efficiency has been measured and it is significantly high in all load and line
conditions (see
conditions (see
). At full load, the efficiency is higher than 85% at any input voltage,
making this design suitable for high efficiency power supplies. Also, at lower output load the
efficiency is better than 82%. At minimum load (40 mA output current) the efficiency is still
good.

shown, the voltage regulation over the entire input voltage range is excellent at any output
current level.
