FAN53555−24, −08, and −09 Reduced Output Current (4 A Max. RMS. for 08, and 24, 3 A Max. RMS for

09) Smaller Footprint Application

The FAN53555−24, −08, and −09 were developed to provide power for core processors with high−performance graphics

acceleration in Li−Ion−powered handheld devices. These applications require a very compact solution. The smaller input and

output capacitors in the table below assume that additional bypass capacitance exists across the battery in fairly close proximity

PGND (see layout recommendations in Figure 2 below).
