*2. VOUT(E): Actual output voltage
VOUT(S): Specified output voltage
*3. The output current at which the output voltage becomes 97 % of VOUT(E) after gradually increasing the
output current.
*4. Design assurance
*5. The ideal efficiency is indicated by the following expression.
Efficiency ()=(VOUT IOUT) / (2.0 VIN IOUT)
