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 compact 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.
