Product Description
Product Overview
The AUP052N085, AUB050N085, and AUN045N085 are N-Channel Silicon MOSFETs designed for efficient switching applications. These enhancement-mode MOSFETs are easy to control and feature low drain-source on-resistance (RDS(ON)). They are ideal for use in single-ended flyback or two-transistor forward topologies, commonly found in PC power supplies, PD adaptors, LCD & PDP TVs, and LED lighting systems.
