Product Description
Texas Instruments UC2854BN is a Power Factor Pre-Regulator Circuit IC designed for power factor correction (PFC) applications. It operates at a switching frequency of 115 kHz with 16-pin PDIP (Plastic Dual In-line Package) and through-hole mounting style, supporting supply voltages from 10 V minimum to 20 V maximum. This IC features a low start-up supply current of 300 μA and a maximum source current of 14 μA, delivering efficient power control with typical supply current of 18 mA during normal operation.
The device supports a wide operating temperature range from -40°C to 85°C, enabling reliable performance under industrial and commercial environments. Its compact package size of 19.3 mm length by 4.57 mm height facilitates easy PCB integration.
Power factor correction is critical in AC-DC power supplies to improve energy efficiency and comply with harmonic current regulations. The UC2854BN controller meets IEC61000-3-2 harmonic current limit standards, providing high power factor, low current distortion, and improved power density for electronic equipment.
This IC is suitable for use in industrial, commercial, and consumer power electronics requiring power management optimization. Its advanced internal circuitry enables stable and efficient pre-regulation in power factor correction converters.
Starts with minimal current, conserving energy during power up. Operates reliably across extended temperature ranges for diverse conditions. Compact and standardized PDIP packaging for easy replacement and design flexibility.
Designed explicitly for power factor correction in AC/DC power supplies. Provides improved harmonic performance and higher efficiency in power systems. Environmentally compliant, but no specific certifications stated. Explore the full range of Power Management ICs for enhanced electronic circuit control and efficiency at EnvMart.
