Description
Key features of the UCC28064ADR include two complementary gate drive outputs, zero crossing detection, and advanced protection mechanisms such as overcurrent protection, UVLO (Under-Voltage Lockout), and overvoltage protection. It also supports programmable frequency dithering to reduce EMI (Electromagnetic Interference) and improve system reliability.
The device is typically used in high-power applications such as industrial power supplies, telecom rectifiers, and LED drivers. Its compact design and robust feature set make it an attractive choice for engineers looking to improve power factor and efficiency in their power supply designs. The UCC28064ADR is available in a small-form-factor SOIC package, making it suitable for space-constrained applications.
