UC1851  
UC2851  
UC3851  
Programmable, Off-Line, PWM Controller  
FEATURES  
DESCRIPTION  
All Control, Driving, Monitoring, and Protection  
Functions Included  
The UC1851 family of PWM controllers are optimized for off-  
line primary side control. These devices include a high current  
totem pole output stage and a toggle flip-flop for absolute 50%  
duty cycle limiting. In all other respects this line of controllers is  
pin for pin compatible with the UC1841 series. Inclusion of all  
major housekeeping functions in these high performance con-  
trollers makes them ideal for use in cost sensitive applications.  
Low-Current Off Line Start Circuit  
Voltage Feed Forward or Current Mode Control  
High Current Totem Pole Output  
50% Absolute Max Duty Cycle  
Important features of these controllers include low current  
start-up, linear feed-forward for constant volt-second operation,  
and compatibility with both voltage or current mode control. In  
addition, these devices include a programmable start thresh-  
old, as well as programmable over-voltage, under-voltage, and  
over current fault thresholds. The fault latch on these devices  
can be configured for automatic restart, or latched off response  
to a fault.  
PWM Latch for Single Pulse Per Period  
Pulse-by-Pulse Current Limiting plus Shutdown  
for Over-Current Fault  
No Start-Up or Shutdown Transients  
Slow Turn-On Both Initially and After Fault  
Shutdown  
These devices are packaged in 18-pin plastic or ceramic dual-  
in-line packages, or for surface mount applications, a 20 Pin  
PLCC. The UC1851 is characterized for -55°C to +125°C op-  
eration while the UC2851 and UC3851 are designed for -40°C  
to +85°C and 0°C to +70°C, respectively.
