TA = +25°C, VIN = PVCC (PVCC = 5V for 18VIN), CIN = 220µFx1, 10µF/Ceramicx2, COUT = 330µF (ESR = 10m),
22µF/Ceramicx3. The efficiency equation is: Efficiency = O---I--n-u---pt---p-u--u--t--t--P--P--o---o-w---w--e---e-r---r = -P---P-O---I-U-N---T-- = ---V----O--V---U-I--N-T----xx---II--OI--N--U-----T----
