UCC28063
Description
Optimized for consumer applications concerned with audible noise elimination, this solution extends the advantages of transition mode - high efficiency with low-cost components - to higher power ratings than previously possible. By utilizing a Natural Interleaving™ technique, both channels operate as masters (that is, there is no slave channel) synchronized to the same frequency.
Key Features
- Input Filter and Output Capacitor Ripple-Current Cancellation - Reduced Current Ripple for Higher System Reliability and Smaller Bulk Capacitor - Reduced EMI Filter Size
- Phase Management Capability
- Fail-Safe OVP with Dual Paths Prevents Output Overvoltage Conditions by Voltage-Sensing Failures
- Sensorless Current-Shaping Simplifies Board Layout and Improves Efficiency
- Advanced Audible Noise Performance
- Non-linear Error-Amplifier Gain
- Soft Recovery on Overvoltage
- Integrated Brownout and Dropout Handling
- Reduced Bias Currents
- Improved Efficiency and Design Flexibility Over Traditional Single-Phase Continuous Conduction Mode (CCM)
