General Description
The AOZ5616QI 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 AOZ5616QI uses PWM input for accurate control of
the power MOSFETs switching activities, is compatible
with 5V logic and supports Tri-State PWM.
A number of features are provided which make the
AOZ5616QI 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.
