    • Low RDS(ON) for Internal Switches (Top/Bottom): 35/15mΩ
    • 2.7-5.5V Input Voltage Range
    • Pseudo-constant Frequency: 1MHz
    • External Adjustable Soft-start Limits the Inrush Current
    • Power Good Indicator
    • Output Auto Discharge at Shutdown
    • Latch off Protection under Short Circuit and OVP Conditions
    • RoHS Compliant and Halogen Free
    • Compact Package: QFN2x2-10
    • Built-in Over-temperature Protection

     The SY20268 is a high efficiency 1MHz synchronous step-down DC/DC regulator capable of delivering up to 6A output current.

    The SY20268 operates over a wide input voltage range from 2.7V to 5.5V and integrates main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
