Texas Instruments UC3854NG4 is a high-performance controller for active Power Factor Correction (PFC) circuits. This device operates in average current mode, enabling precise control of input current to achieve a power factor close to unity. With a switching frequency of up to 200kHz, it facilitates the use of smaller, more efficient external components. The UC3854NG4 features a voltage feed-forward function, which improves transient response to line voltage variations. It also includes over-voltage protection, undervoltage lockout, and a latching current limit for robust operation. This through-hole component, packaged in a 16-pin DIP, is suitable for applications requiring efficient power conversion, such as in AC-DC power supplies for computing, industrial automation, and lighting systems. The operating temperature range is 0°C to 70°C, with a supply voltage range of 14.5V to 30V. The device has a typical startup current of 1.5mA.
