TDA21106 is a power management chip launched by Dinghao Electronics. It supports a maximum frequency of 2MHz and can withstand more than 4A peak currents. It is an ideal choice for desktop CPU power supplies and VRMs.
The TDA21106 is a dual high‑speed driver designed to drive N‑Channel low‑side and high‑side MOSFETs in half‑bridge configurations. It offers fast rise and fall times, adjustable high‑side gate drive voltage, and built‑in protection features, making it suitable for high‑efficiency DC/DC converters, motor drives, and Class‑D audio applications.
The datasheet details absolute maximum ratings, thermal and electrical characteristics, dynamic switching parameters, and package dimensions (P‑DSO‑8). It also includes a timing diagram, pin‑out description, and ordering information for designers needing precise performance data.
