DC-DC Buck Modules
Status: Full Production
The AOZ29303QI is a versatile, wide-operating range, high-efficiency, and easy-to-use power module that integrates a buck converter, inductor, and passive components into a compact QFN package. It features a wide input range from 4.5V to 30V and provides up to 3A of continuous output current. It supports high duty cycle operation up to 87%. This power module is configurable using a few external components. External compensation allows the user to optimize the module for a wide range of transient response requirements and output capacitance.
