AOZ29303QI Datasheet | Alpha & Omega Semiconductors

Description The AOZ29303QI is a versatile, wide operating range, highefficiency, easy-to-use power module that integrates a buck converter, inductor, and passive ponents into a pact QFN package. The highly integrated solution significantly simplifies design efforts and enables faster time to market. The AOZ29303QI works from a wide input range of 4.5 V to 30 V and provides up to 3 A of continuous output current. It supports high duty cycle operation up to 87%. This power module is configurable using a few external ponents. Output voltage can be set by using a resistor divider. Soft start is programmable using an external capacitor. The switching frequency can be set from 200 k Hz to 1 MHz with an external resistor. External pensation allows the user to optimize the module for a wide range of transient response requirements and output capacitance.
