AOZ5653BQI Datasheet | Alpha & Omega Semiconductors

Description The AOZ5653BQI 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 4 mm x 4 mm QFN package is optimally chosen and designed to minimize parasitic inductance for minimal EMI signature. Drop-in design for TDA21240. The AOZ5653BQI uses PWM input for accurate control of the power MOSFETs switching activities, is patible with 3.3 V logic. A number of features are provided making the AOZ5653BQI a highly versatile power module. The boot- strap switch is integrated in the driver. The pin-out is also optimized for low parasitics, keeping their effects to a minimum.
