3 / 15 page  IRDC3146EVAL 3 Rev.1.0 7/28/04 www.irf.com The PCB is 4-layers FR4 board, the top layer is dedi- cated for power components, with two parallel control MOSFETs and two parallel Synchronous MOSFETs. These MOSFETs are dual layout for both SOIC-8 and DirectFET footprint. The input capacitors are all located close to MOSFETs. The two output inductors are lo- cated closed to MOSFETs and are symmetrical to the output connector for more accurate current sharing re- sult. The two mid-layers are dedicated for Analog and Power ground, these two grounds are kept separated from each other and they are connected at a single point as shown in Figure3. All the decoupling capacitors, charge pump capacitor and feedback components are located close to the IC. The feedback resistors are tied to the output voltage at the point of regulation.
