UCG2882x High Frequency QR Flyback Converters

Texas Instruments UCG2882x High-Frequency Quasi-Resonant (QR) Flyback Converters feature a built-in 750V GaN high-electron-mobility transistor (HEMT) with a low Rds(on) of 170mΩ, enabling efficient AC-to-DC power conversion. The UCG2882x is designed for high-power-density applications, such as cell phone fast chargers and notebook adapters. The key feature of this device is its self-bias and auxiliary-less sensing scheme, which eliminates the need for an auxiliary winding and simplifies system design with higher efficiency.
