AOZ5612BQI Datasheet | Alpha & Omega Semiconductors

Description The AOZ5612BQI 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 pact 5mm x 5mm QFN package is optimally chosen and designed to minimize parasitic inductance for minimal EMI signature. The AOZ5612BQI uses PWM and/or SMOD# input for accurate control of the power MOSFETs switching activities, is patible with 3V logic and supports Tri State PWM. A number of features are provided making the AOZ5612BQI 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.
