AOZ53071QI High-Current, High-Performance DrMOS Power Module General Description The AOZ53071QI 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 AOZ53071QI uses a PWM input for accurate control of the power MOSFETs switching activities, is compatible with 3 V and 5 V (CMOS) logic and supports Tri-State PWM. Features • 2.5 V to 25 V power supply range • 4.5 V to 5.
