UC3853  
High Power Factor Preregulator  
DESCRIPTION  
FEATURES  
Complete 8-pin Power Factor  
Solution  
The UC3853 provides simple, yet high performance active power factor  
correction. Using the same control technique as the UC1854, this 8-pin de-  
vice exploits a simplified architecture and an internal oscillator to minimize  
external component count. The UC3853 incorporates a precision multi-  
plier/squarer/divider circuit, voltage and current loop error amplifiers, and a  
precision voltage reference to implement average current mode control  
with RMS line voltage compensation. This control technique maintains con-  
stant loop gain with changes in input voltage, which minimizes input line  
current distortion over the worldwide input voltage range.  
Reduced External Components  
RMS Line Voltage Compensation  
Precision Multiplier/Squarer/Divider  
Internal 75kHz Synchronizable  
Oscillator  
The internal 75kHz oscillator includes an external clock input, allowing syn-  
chronization to downstream converters. Additionally, the device features an  
overvoltage protection comparator, a clamped MOSFET gate driver which  
self-biases low during undervoltage lockout, and low startup and supply  
Average Current Mode PWM  
Control  
Overvoltage Protection Comparator  
High Current, Clamped Gate Driver current.  
These devices are available in 8-pin plastic and ceramic dual in-line (DIP)  
packages, and 8-lead small outline (SOIC) packages. The UC1853 is  
specified for operation from –55°C to +125°C, the UC2853 is specified for  
operation from –25°C to +85°C, and the UC3853 is specified for operation  
from 0°C to +70°C.
