SNVS480J January 2007 – July 2020 LM5022
A reasonable estimation for the efficiency of a boost regulator controlled by the LM5022 can be obtained by adding together the loss is each current carrying element and using Equation 58.
The following shows an efficiency calculation to complement the circuit design. Output power for this circuit is 40 V × 0.5 A = 20 W. Input voltage is assumed to be 13.8 V, and the calculations used assume that the converter runs in CCM. Duty cycle for VIN = 13.8 V is 66%, and the average inductor current is 1.5 A.
