ISL8200MM
Typical Performance Characteristics
Efficiency Performance
TA = +25°C, PVIN = VIN, CIN = 220µFx1, 10µF/Ceramic x 2, COUT = 47µF/Ceramic x 8.
The efficiency equation is: Efficiency = O------u---t---p---u----t----P-----o----w-----e----r = P-----O----U----T-- = (---V----O-----U----T----x---I--O----U-----T----)
