    • 4 A output current
    • 4.0 V to 18 V input voltage
    • Output voltage adjustable from 0.8 V to 0.88 x VIN
    • 500 kHz switching frequency
    • High efficiency at light load
    • Programmable soft-start and enable
    • Integrated 95 mW and 69 mW power MOSFETs
    • All ceramic capacitor
    • Power Good
    • Cycle-by-cycle current limiting
    • Short-circuit protection
    • Hysteretical thermal shutdown
    • RoHS compliant
