AOZ5116QI-03

DrMOS + Smart Power Stages (SPS)

Status: New

The AOZ5116QI-03 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. AOZ5116QI-03 comes with low noise technology enhancement at switching node to reduce noise interference.
