FEATURES  
APPLICATIONS  
Interleaved Average Current-Mode PWM  
Control with Inherent Current Matching  
High-Efficiency Server and Desktop Power  
Supplies  
Advanced Current Synthesizer Current  
Sensing for Superior Efficiency  
Telecom Rectifiers  
White Goods and Industrial Equipment  
Highly-Linear Multiplier Output with Internal  
Quantized Voltage Feed-Forward Correction  
for Near-Unity PF  
DESCRIPTION  
The UCC28070 is an advanced power factor  
correction device that integrates two pulse-width  
modulators (PWMs) operating 180° out of phase.  
Programmable Frequency (30 kHz to 300 kHz)  
Programmable Maximum Duty-Cycle Clamp  
This  
interleaved  
PWM  
operation  
generates  
Programmable Frequency Dithering Rate and  
Magnitude for Enhanced EMI Reduction  
substantial reduction in the input and output ripple  
currents, and the conducted-EMI filtering becomes  
easier and less expensive. A significantly improved  
multiplier design provides a shared current reference  
to two independent current amplifiers that ensures  
matched average current mode control in both PWM  
outputs while maintaining a stable, low-distortion  
sinusoidal input line current.  
Magnitude: 3 kHz to 30 kHz  
Rate: Up to 30 kHz  
External Clock Synchronization Capability  
Enhanced Load and Line Transient Response  
through Voltage Amplifier Output Slew-Rate  
Correction  
The UCC28070 contains multiple innovations  
including current synthesis and quantized voltage  
feed-forward to promote performance enhancements  
in PF, efficiency, THD, and transient response.  
Features including frequency dithering, clock  
synchronization, and slew rate enhancement further  
expand the potential performance enhancements.  
Programmable Peak Current Limiting  
Bias-Supply UVLO, Over-Voltage Protection,  
Open-Loop Detection, and PFC-Enable  
Monitoring  
External PFC-Disable Interface  
Open-Circuit Protection on VSENSE and  
VINAC pins  
The UCC28070 also contains a variety of protection  
features including output over-voltage detection,  
programmable peak-current limit, under-voltage  
lockout, and open-loop protection.
