Description
The UC1854 is an active power factor correction (PFC) controller that provides high power factor (up to 0.99) and low line current distortion (less than 5%). It uses average current-mode control to achieve fixed-frequency current control with stability and low distortion. The UC1854 also features a high reference voltage and high oscillator amplitude to minimize noise sensitivity, and fast PWM elements to permit chopping frequencies above 200kHz. It can be used in single and three-phase systems with line voltages ranging from 75 to 275 volts and line frequencies from 50Hz to 400Hz.
Features
Control Boost PWM to 0.99 Power Factor
Limit Line Current Distortion To <5%
World-Wide Operation Without Switches
Feed-Forward Line Regulation
Average Current-Mode Control
Low Noise Sensitivity
Low Start-Up Supply Current
Fixed-Frequency PWM Drive
Low-Offset Analog Multiplier/Divider
1A Totem-Pole Gate Driver
Precision Voltage Reference
Applications
Power supplies
PFC pre-regulators
Industrial automation
Lighting systems
Motor drives
