Description

**DESCRIPTION**
The UCC28510 series of combination PFC/PWM controllers provide complete control functionality for any off-line power system requiring compliance with the EC1000−3−2 harmonic
reduction requirements. By combining the control and drive signals for the PFC and the PWM stages into a single device, significant performance and cost benefits are gained. By managing the modulation mechanisms of the two stages (leading-edge modulation for PFC and
trailing-edge modulation for PWM), the ripple current in the boost capacitor is minimized.
**FEATURES**
**Provides Control of PFC and PWM Power ****Stages In One Device**
**Leading-Edge PFC, Trailing-Edge PWM ****Modulation for Reduced Ripple**
**Built-In Sequencing of PFC and PWM ****Turn-On**
**2-A Source and 3-A Sink Gate Drive for Both ****PFC and PWM Stages**
**Typical 16-ns Rise Time and 7-ns Fall Time ****into 1-nF Loads**
**PFC Features**
**− Average-Current-Mode Control for ****Continuous Conduction Mode Operation**
**− Highly-Linear Multiplier for Near-Unity ****Power Factor**
**− Input Voltage Feedforward Implementation**
**− Improved Load Transient Response**
**− Accurate Power Limiting**
**− Zero Power Detect**
**PWM Features**
**− Peak-Current-Mode Control Operation**
**− 1:1 or 1:2 PFC:PWM Frequency Options**
**− Programmable maximum duty cycle**
**− Programmable Soft-Start**
**− Two Hysteresis Options for Differing ****Hold-Up Time Requirements**
