  • The AOZ5039QI is a high efficiency synchronous buck

    power stage module consisting of two asymmetrical

    MOSFETs and an integrated driver.The MOSFETs are

    individually optimized for operation in the synchronous

    buck configuration. The high side MOSFET is optimized

    to achieve low capacitance and gate charge for fast

    switching with low duty cycle operation. The low side

    MOSFET has ultra low ON resistance  to minimize

    conduction loss. The compact 5mm x 5mm QFN

    package is optimally chosen and designed to minimize

    parasitic inductance for minimal EMI signature.

    The AOZ5039QI is intended for use with TTL and Tri-state compatibility by using both the PWM and/or FCCM

    inputs for accurate control of the powerMOSFETs.

    A number of features are provided making the

    AOZ5039QI a highly versatile power module: The

    bootstrap diode is integrated in the driver.The low side

    MOSFET can be driven into diode emulation mode to

    provide asynchronous operation when required.The pin-out is optimized for low inductance routing of the

    converter, keeping the parasitics and their effects to a

    minimum
