Texas Instruments UCC2818AD Power Factor Correction Controller

The UCC2818AD from Texas Instruments is a versatile and robust Power Factor Correction (PFC) controller designed for use in AC-to-DC power supplies. This integrated circuit is engineered to provide low total harmonic distortion and high power factor, resulting in an efficient power supply system that meets global power quality standards.

Featuring an average current mode control, the UCC2818AD offers precise power regulation and simple external loop compensation. Its wide operating range of -40°C to +85°C ensures reliable performance across various environmental conditions, making it suitable for industrial and commercial applications.

The device is housed in a 16-pin SOIC package, providing a compact solution for space-constrained applications. It operates over a wide input voltage range and is capable of handling high power levels, which makes it an excellent choice for applications such as offline power supplies, power adapters, and power conditioning systems.

Key features of the UCC2818AD include:

• Programmable soft-start function that reduces stress on the input power source during startup.
• Low startup and operating current, which enhances the overall efficiency of the power supply.
• Integrated under-voltage lockout with hysteresis for improved system reliability.
• Feedforward line regulation that minimizes output voltage variations due to changes in the input voltage.
• OVP (Over Voltage Protection) and brownout protection to safeguard the system against voltage anomalies.

The UCC2818AD also includes a multitude of protection features such as peak current limit and over-temperature shutdown, which contribute to a safer and more reliable operation. Its advanced control methodology enables power supply designers to achieve an optimal balance between efficiency and performance, making it a preferred choice for forward-thinking power management solutions.

As a product of Texas Instruments, a leader in semiconductor solutions, the UCC2818AD is backed by extensive support and documentation, ensuring a seamless integration into your power management system.
