8-Pin Continuous Conduction Mode (CCM) PFC Controller  
FEATURES  
DESCRIPTION  
•
8-pin Solution Without Sensing Line Voltage  
Reduces External Components  
The UCC28019 8-pin active Power Factor Correction  
(PFC) controller uses the boost topology operating in  
Continuous Conduction Mode (CCM). The controller  
is suitable for systems in the 100 W to >2 kW range  
over a wide-range universal AC line input. Startup  
current during under-voltage lockout is less than 200  
µA. The user can control low power standby mode  
by pulling the VSENSE pin below 0.77 V.

Wide-Range Universal AC Input Voltage  
Fixed 65-kHz Operating Frequency  
Maximum Duty Cycle of 97%  
Output Over/Under-Voltage Protection  
Input Brown-Out Protection  
Low-distortion wave-shaping of the input current  
using average current mode control is achieved  
without input line sensing, reducing the Bill of  
Materials component count. Simple external  
networks allow for flexible compensation of the  
current and voltage control loops. The switching  
frequency is internally fixed and trimmed to better  
than ±5% accuracy at 25°C. Fast 1.5-A gate peak  
current drives the external switch.  
Cycle-by-Cycle Peak Current Limiting  
Open Loop Detection  
Low-Power User Controlled Standby Mode  
APPLICATIONS  
•
CCM Boost Power Factor Correction Power  
Converters in the 100 W to >2 kW Range  
Server and Desktop Power Supplies  
Telecom Rectifiers  
Industrial Electronics  
Home Electronics

Numerous system-level protection features include  
peak current limit, soft over-current, open-loop  
detection,  
input  
brown-out,  
output  
over/under-voltage, a no-power discharge path on  
VCOMP, and overload protection on ICOMP.  
Soft-Start limits boost current during start-up. A  
trimmed internal reference provides accurate  
protection thresholds and regulation set-point. An  
internal clamp limits the gate drive voltage to 12.5 V.
