The UCC3818D from Texas Instruments is a BiCMOS Power Factor Preregulator (PFC) controller designed to shape AC input line current waveforms to match the AC input line voltage, achieving near-unity power factor. It utilizes Average Current Mode control for stable, low-distortion sinusoidal line current.
Key electrical specifications include an operating frequency range of 6 kHz to 220 kHz, a typical start-up current of 150 µA, and operation up to 18 V. The UCC3818D features a CCM control mode with a maximum duty cycle of 100% and specific UVLO voltages of 10.5 V / 10 V for the UCC2818 variant.
This component is housed in a SOIC (16) package and is designed for surface mount applications. It is suitable for various power supply applications, including PC power, consumer electronics, lighting, and industrial power supplies, particularly those requiring IEC6100-3-2 compliance for supplies less than 300 W.
The maximum operating voltage is 18 V.
It is available in a 16-pin SOIC package.
The operating frequency range is 6 kHz to 220 kHz.
The typical start-up current is 150 µA.
The UVLO thresholds are 10.5 V (on) and 10 V (off).
It uses average current mode control in continuous conduction mode (CCM).
The maximum duty cycle is 100%.
