The Texas Instruments UCC2818AD is an active power factor corrected preregulator controller. It is designed to shape the AC input line current waveform to correspond to the AC input line voltage, achieving near-unity power factor. This controller utilizes average current mode control for stable, low distortion sinusoidal line current.
Key electrical specifications include a frequency range of 6 kHz to 220 kHz and a maximum duty cycle of 100%. It operates with UVLO voltages of 10.5V/10V and features a typical start-up current of 150 µA. The device also includes a smaller gate drive resistor and a low current amplifier offset of ±2 mV.
The UCC2818AD is suitable for 750 W applications and supports continuous control mode with Enable and OVP features. It is designed for worldwide line operation, offering overvoltage protection and accurate power limiting. The controller is built on Texas Instruments' BiCMOS process, providing low power dissipation and improved noise immunity.
Available in multiple package options including SOIC (D), TSSOP (PW), and PDIP (N), the UCC2818AD offers flexibility for various design requirements. The SOIC package measures 59.4 mm², the TSSOP measures 32 mm², and the PDIP measures 181.42 mm².
