FEATURES  
DESCRIPTION  
The UCC28510 series of combination PFC/PWM  
D
D
D
D
D
Provides Control of PFC and PWM Power  
Stages In One Device  
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. By managing the  
modulation mechanisms of the two stages  
(leading-edge modulation for PFC and  
trailing-edge modulation for PWM), the ripple  
current in the boost capacitor is minimized.  
Based on the average current mode control  
architecture with input voltage feedforward of prior  
PFC/PWM combination controllers, these devices  
offer performance advantages. Two new key  
PWM features are programmable maximum duty  
cycle and the 2x PWM frequency options to the  
base PFC frequency. For the PFC stage, the  
devices feature an improved multiplier and the  
use of a transconductance amplifier for enhanced  
transient response.

2-A Source and 3-A Sink Gate Drive for Both  
PFC and PWM Stages

PFC 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  
− 1:1 or 1:2 PFC:PWM Frequency Options  
− Programmable maximum duty cycle  
− Programmable Soft-Start  
− Two Hysteresis Options for Differing  
Hold-Up Time Requirements  
The core of the PFC section is in a three-input  
multiplier that generates the reference signal for  
the line current. The UCC28510 series features a  
highly linearized multiplier circuit capable of  
producing a low distortion reference for the line  
current over the full range of line and load  
conditions. A low-offset, high-bandwidth current  
error amplifier ensures that the actual inductor  
current (sensed through a resistor in the return  
path) follows the multiplier output command  
signal. The output voltage error is processed  
through a transconductance voltage amplifier.
