TL494 Pulse Width Modulation Controller SMD IC

The UC3854 is a High Power Factor Preregulator designed for power management applications, available in an SMD (Surface Mount Device) package. This IC is specifically tailored to improve the power factor in power supply circuits, making it an ideal choice for systems that need to comply with stringent power quality standards. By controlling the input current to follow the shape of the input voltage, the UC3854 significantly reduces harmonic distortion and enhances overall power efficiency. Key features of the UC3854 include a highly accurate analog multiplier and divider circuit for precision control, an error amplifier for voltage regulation, a current amplifier to sense input current, and a high-speed PWM (Pulse Width Modulation) for fast response in regulating power. It also integrates over-voltage, over-current, and under-voltage protection mechanisms, ensuring system safety and reliability. Operating at a wide input voltage range, the UC3854 supports applications from 100V to 400V input levels, making it suitable for use in AC-DC converters, power factor correction (PFC) modules, and industrial power supply units. Its ability to operate at higher switching frequencies enables the design of smaller and more efficient magnetic components.
