AOZ5316NQI
High-Current, High-Performance
DrMOS Power Module General Description Features The AOZ5316NQI 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. 2.5V to 25V power supply range The AOZ5316NQI uses a PWM input for accurate control
of the power MOSFETs switching activities, is compatible
with 3V and 5V (CMOS) logic and supports Tri-State
PWM. SMOD# control for Diode Emulation / CCM operation A number of features are provided making the
AOZ5316NQI 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. Memory and graphic cards 4.5V to 5.5V driver supply range 55A continuous output current -Up to 80A for 10ms on pulse
