AOZ5018QI-C
DrMOS + Smart Power Stages (SPS)
Status: Full Production
AOZ5018QI-C 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 ultralow ON resistance to minimize conduction loss.
