Introduction

AI Translation

The AOZ5018QI is a high-efficiency synchronous buck power stage module consisting of two asymmetric MOSFETs and an integrated driver. These MOSFETs are individually optimized for operation in a synchronous buck configuration. The high-side MOSFET is optimized for low capacitance and low gate charge to enable fast switching at low duty cycle operation. The low-side MOSFET features ultra-low on-resistance to minimize conduction losses. The AOZ5018QI uses a PWM input for precise control of power MOSFET switching activity, is compatible with 5V (CMOS) logic, and supports tri-state PWM. The module also incorporates multiple features that make it a highly capable power module. A bootstrap diode is integrated in the driver. The low-side MOSFET can be driven into diode emulation mode to provide asynchronous operation and improve light-load performance. The pin layout is also optimized for low parasitic effects, minimizing their impact.
