Alpha & Omega AOZ29303QI Step-Down Integrated DC-DC Power Module Datasheet
The AOZ29303QI is a highly integrated step‑down DC‑DC power module that combines a buck converter, inductor and passive components in a compact QFN package. It operates from 4.5 V to 30 V input and delivers up to 3 A continuous output with up to 93 % peak efficiency and 87 % duty‑cycle capability.
The device is configurable via external components: output voltage is set with a resistor divider, soft‑start with a capacitor, and switching frequency (200 kHz‑1 MHz) with a resistor. It includes multiple protection features and is supplied in a 9 mm × 6 mm × 3.7 mm QFN‑48L package suitable for industrial, automotive and networking applications. This manual is written in Chinese.
