AOZ5239QI High-Current, High-Performance DrMOS Power Module General Description The AOZ5239QI 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 compact 5x5 QFN package is optimally designed to minimize parasitic inductance for minimal EMI signature. The AOZ5239QI is compatible with 3.3V and 5V PWM logic with Mid-state levels compatibility by using both the PWM and/or SMOD# can be used to control the power MOSFETs.
