UCC28515 Overview
Description
The UCC28510 series of combination PFC/PWM controllers provide complete control functionality for any off-line power system requiring compliance with the IEC1000-3-2 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.
Key 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
- Programmable maximum duty cycle
- Programmable Soft-Start
- Two Hysteresis Options for Differing Hold-Up Time Requirements
