APPLICATIONS INFORMATION  
A 250W PREREGULATOR  
The circuit of Figure 1 shows a typical application of the  
UC3854 as a preregulator with high power factor and effi-  
ciency. The assembly consists of two distinct parts, the  
control circuit centering on the UC3854 and the power  
section.  
The power section is a "boost" converter, with the induc-  
tor operating in the continuous mode. In this mode, the  
duty cycle is dependent on the ratio between input and  
output voltages; also, the input current has low switching  
frequency ripple, which means that the line noise is low.  
Furthermore, the output voltage must be higher than the  
peak value of the highest expected AC line voltage, and  
all components must be rated accordingly.  
cycle of this output is simultaneously controlled by four  
separate inputs to the chip:  
INPUT  
PIN #  
FUNCTION  
VSENSE........................11 .......... Output DC Voltage  
IAC.................................6 .......... LineVoltage Waveform  
ISENSE/Mult Out .........4/5 .......... Line Current  
VRMS.............................8 .......... RMS Line Voltage  
Additional controls of an auxiliary nature are provided.  
They are intended to protect the switching power MOS-  
FETS from certain transient conditions, as follows:  
INPUT  
PIN #  
FUNCTION  
ENA ............................10 .......... Start-Up Delay  
SS...............................13 .......... Soft Start  
PKLIM...........................2 .......... Maximum Current Limit  
In the control section, the UC3854 provides PWM pulses  
(GT Drv, Pin 16) to the power MOSFET gate. The duty
