AOZ5507QI
High-Current, High-Performance
DrMOS Power Module
General Description
AOZ5507QI 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.
AOZ5507QI uses a PWM 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
AOZ5507QI a highly versatile power module. The
bootstrap switch 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.
