used to keep input power constant with varying input  
voltage. Generation of V is accomplished using I in  
conjunction with an external single-pole filter. This not  
only reduces external parts count, but also avoids the  
use of high-voltage components, offering a lower-cost  
solution. The multiplier then divides the line current by

The dc-to-dc section relies on an error signal generated  
on the secondary-side and processes it by performing  
peak current mode control. The dc-to-dc section also  
features current limiting, a controlled soft-start, preset  
operating range with selectable options, and 50%  
maximum duty cycle.  
DESCRIPTION  
The UCC2850x family provides all of the control  
functions necessary for an active power-factor-  
corrected preregulator and a second-stage dc-to- dc  
converter. The controller achieves near-unity power  
factor by shaping the ac input line current waveform to  
correspond to the ac input-line voltage using average  
current-mode control. The dc-to-dc converter uses  
peak current-mode control to perform the step-down  
power conversion.  
The UCC28500 and UCC28502 have a wide UVLO  
threshold (16.5 V/10 V) for bootstrap bias supply  
operation. The UCC28501 and UCC28503 are  
designed with a narrow UVLO range (10.5 V/10 V) more  
suitable for fixed bias operation. The UCC28500 and  
UCC28501 have a narrow UVLO threshold for PWM  
stage (to allow operation down to 75% of nominal bulk  
voltage), while the UCC28502 and UCC38503 are  
configured for a much wider operation range for the  
PWM stage (down to 50% of bulk nominal voltage).  
The PFC stage is leading-edge modulated while the  
second stage is trailing-edge synchronized to allow for  
minimum overlap between the boost and PWM  
switches. This reduces ripple current in the bulk-output  
capacitor.In order to operate with over three-to-one
