(1) Average efficiency of four load points, IOUT = 100%, 75%, 50% and 25% of rated full-load current for each respective output voltage. Also the 4 point efficiency numbers are measured with MP6951 for better 9V & 5V performance. MP6908 and MP6951 are pin to pin and can be swapped on the EVM.
(2) The voltage ripple numbers mentioned above include switching noise. Without this it is less than 150mVpp. Please refer section on "Section 3.3.9".
