AOZ5311NQI-04

AOZ5311NQI-04

DrMOS + Smart Power Stages (SPS)

The AOZ5311NQI-04 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.
