AOZ5332QI (AL00)

AOZ5332QI
Alpha & Omega Semiconductor
High-Current, High-Performance DrMos Power Module
Package Type: 5x5 QFN-31L

The AOZ5332QI 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 AOZ5332QI 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. A number of features are provided making the AOZ5332QI 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.
