    Functional safety category
    •      Low RDS(ON) for Internal Switches (Top/Bottom): 270mΩ/160mΩ
    •      2.5~5.5V Input Voltage Range
    •      High Switching Frequency 3.0MHz Minimizes the External Components
    •      Internal Soft-start Limits the Inrush Current
    •     100% Dropout Operation
    •      RoHS Compliant and Halogen Free
    •      Compact Package: SOT23-5

    SY20108 is a high efficiency 3MHz synchronous step down DC/DC regulator IC capable of delivering up to 1A output current. It can operate over a wide input voltage range from 2.5V to 5.5V and integrate main switch and synchronous switch with very low RDS(ON) to minimize the conduction loss.
