AOZ5517MQI

DrMOS + Smart Power Stages (SPS)

Status: Full Production

The AOZ5517MQI 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 5mm x 5mm QFN package is optimally chosen and designed to minimize parasitic inductance for minimal EMI signature.
