AN-SY8063

Applications Note: AN_SY8063 High Efficiency 1 MHz, 3.5A Synchronous Step Down Regulator Preliminary Specification General Description Features The SY8063 is a high-efficiency 1 MHz synchronous step-down DC-DC regulator IC capable of delivering up to 3.5A output current. The SY8063 operates over a wide input voltage range from 2.7V to 5.5V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. Low output voltage ripple and small external inductor and capacitor sizes are achieved with 1MHz switching frequency. Low RDS(ON) for internal switches (top/bottom): 85/65m< 2.7-5.5V input voltage range 1 MHz switching frequency minimizes the external components Internal softstart limits the inrush current 100% dropout operation Power good indicator RoHS Compliant and Halogen Free Compact package: DFN3x3-10 Ordering Information SY8063□(□□)□ Temperature Code Package Code Optional Spec Code Temperature...
