Overview
AOZ5516QI-02 High-Current, High-Performance DrMOS Power Module General Description The AOZ5516QI-02 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 AOZ5516QI-02 uses PWM and/or FCCM input for accurate control of the power MOSFETs switching activities, is compatible with 5V (CMOS) logic and supports Tri-State PWM.
A number of features are provided making the AOZ5516QI-02 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 and improve light-load performance.
The pin-out is also optimized for low parasitics, keeping their effects to a minimum.
