AOZ5613QI Datasheet | Alpha & Omega Semiconductors

Description The AOZ5613QI 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 AOZ5613QI uses PWM input for accurate control of the power MOSFETs switching activities, is patible with 5V logic and supports Tri-State PWM. A number of features are provided which make the AOZ5613QI 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.
