Infineon TDA21201 Integrated Switch Preliminary Data Sheet
The Integrated Switch TDA21201 combines a MOSFET driver, a high‑side MOSFET and a low‑side MOSFET in one TO‑220 or TO‑263 package, enabling a compact, efficient power stage for 12 V to sub‑3.3 V DC‑DC converters. It eliminates external bootstrap components and reduces part count, board space, and design complexity.
The document lists absolute maximum ratings, thermal characteristics, electrical parameters, and layout recommendations, and includes typical application circuits for multi‑phase converters, shutdown operation, and current‑sense methods.
