  • Product introduction

The UC2853A provides simple, yet high-performance active power factor correction. As the UC1854 uses the same control technology, this 8-pin device utilizes a simplified architecture and internal oscillator to reduce external component count. Precision UC2853A multiplier/square/divider circuitry, voltage and current loop error amplifier, high accuracy voltage reference and RMS average line voltage compensation current mode control are implemented. This control technique keeps closed-loop gain while maintaining the input voltage, minimizing the worldwide variation in input voltage input line current distortion.

The internal 63kHz oscillator includes an external clock input that allows synchronization to downstream converters.
