General Description

The AOZ29303QI is a versatile, wide operating range, highefficiency,

easy-to-use power module that integrates a buck

converter, inductor, and passive components into a compact

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

components. 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 kHz

to 1 MHz with an external resistor. External compensation

allows the user to optimize the module for a wide range of

transient response requirements and output capacitance.
