Applications Note: AN_SY8805A High Efficiency 1 MHz, 5A Synchronous Step Down Regulator General Description The SY8805A is a high-efficiency 1 MHz synchronous step-down DC-DC regulator, Current Mode Control IC capable of delivering up to 5A output current. The SY8805A operates over a wide input voltage range from 3V to 5.5V. It integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. High intergrated solution and DFN2x2-8 package perform the optimized BOM cost and reduce external ponent part count. Low input and output voltage ripple, small external inductor and capacitor sizes, small PCB layout space are achived with 1MHz switching...
