Infineon TDA21302 Datasheet
The TDA21302 is a multi‑phase DC‑DC buck‑converter controller designed for GHz‑class CPU voltage regulation. It integrates all control functions needed for 2‑to‑4 interleaved buck stages, offering high output current, low ripple, and efficient thermal performance.
Key features include automatic phase selection, active droop compensation, programmable switching frequency (50 kHz‑400 kHz), over‑current protection, and a built‑in voltage‑identification DAC. Typical applications are Intel processor voltage regulators, low‑output‑voltage high‑current DC‑DC converters, and voltage‑regulator modules.
