The Texas Instruments UC3855AN is a high-performance Pulse Width Modulator (PWM) controller designed for advanced Power Factor Correction (PFC) applications. This Through Hole component operates in Average Current mode, enabling precise control and efficient power conversion. With a switching frequency of up to 500kHz, the UC3855AN is well-suited for compact power supply designs. Its low startup current of 150 µA facilitates efficient operation from a wide supply voltage range of 15.5V to 20V. The UC3855AN is packaged in a 20-PDIP (0.300", 7.62mm) configuration and is suitable for operation in ambient temperatures from 0°C to 70°C. This component is commonly utilized in power supplies for computing, industrial automation, and telecommunications equipment.
