AOZ5517QI-02
High-Current, High-Performance
DrMOS Power Module
General Description
The AOZ5517QI-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 AOZ5517QI-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
AOZ5517QI-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.
