DESCRIPTION The UC3853 provides simple, yet high performance active power factor correction. Using the same control technique as the UC1854, this 8-pin device exploits a simplified architecture and an internal oscillator to minimize external ponent count. The UC3853 incorporates a precision multiplier/squarer/divider circuit, voltage and...
