Product details

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 component count.

Features

Complete 8-pin Power Factor Solution.
Reduced External Components.
RMS Line Voltage Compensation.
Precision Multiplier/Squarer/Divider.
Internal 75kHz Synchronizable Oscillator.
Average Current Mode PWM Control.
Overvoltage Protection Comparator.
High Current, Clamped Gate Driver.
