AOZ5505QI

High-Current, High-Performance DrMOS Power Module

Status: New

AOZ5505QI 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.
