CXSD62511 is a high efficiency 1.2MHz synchronous step down DC/DC regulator capable of delivering up to 6A output current. It operates over a wide input voltage range from 2.7V to 6.5V. It integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss. High integrated solution and DFN2x2-8 package perform the optimized BOM cost and reduce external component part count. Low input and output voltage ripple, small external inductor and capacitor sizes, small PCB layout space are achieved.
· Low RDS(ON) for Internal Switches (Top/Bottom): 38/15 mΩ
· 2.7-6.5V Input Voltage Range
· 1.2 MHz Switching Frequency Minimizes the External Components
· Internal Soft-start Limits the Inrush Current
· Up to 94% Efficiency
· 6A Continuous Output Current Capability
· Shutdown Mode Draws<0.1μA Supply Current
· 100% Dropout Operation
· Power Good Indicator
· OCP/UVLO/OTP Protections
· RoHS Compliant and Halogen Free
· Compact Package: DFN2x2-8
· High definition Set Top Box
· LCD TV
· Notebook PC
