Description
The CD3301B is a power management integrated circuit targeted for notebook and portable computer motherboard use. Housed in a 36‑pin QFN package, it is used to regulate and distribute power across various rails in laptop and MacBook board designs. While its internal architecture and ratings haven’t been reliably confirmed from public sources, its presence in laptop spare parts markets suggests roles in core/bus power, control, or sequencing functions.
Because detailed specifications are not widely published, any design or repair usage should verify the part’s behavior via actual measurements or manufacturer/datasheet references.
