  • The AOZ5239QI 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 5x5 QFN package is

    optimally designed to minimize parasitic inductance for

    minimal EMI signature.

    The AOZ5239QI is compatible with 3.3V and 5V PWM

    logic with Mid-state levels compatibility by using both the

    PWM and/or SMOD# can be used to control the power

    MOSFETs.

    The bootstrap diode is integrated in the driver.The low

    side MOSFET can be driven into pulse skip mode to

    provide power saving operation when required.The pin-out is optimized for low inductance routing,keeping the

    parasitics and their effects to a minimum
