Current Mode PWM Controller  
FEATURES  
DESCRIPTION  
Optimized For Off-line And DC  
To DC Converters  
The UC1842/3/4/5 family of control ICs provides the necessary features to  
implement off-line or DC to DC fixed frequency current mode control schemes  
with a minimal external parts count. Internally implemented circuits include  
under-voltage lockout featuring start up current less than 1mA, a precision  
reference trimmed for accuracy at the error amp input, logic to insure latched  
operation, a PWM comparator which also provides current limit control, and a  
totem pole output stage designed to source or sink high peak current. The  
output stage, suitable for driving N Channel MOSFETs, is low in the off state.  
Low Start Up Current (<1mA)  
Automatic Feed Forward  
Compensation  
Pulse-by-pulse Current Limiting  
Enhanced Load Response  
Characteristics  
Differences between members of this family are the under-voltage lockout  
thresholds and maximum duty cycle ranges. The UC1842 and UC1844 have  
UVLO thresholds of 16V (on) and 10V (off), ideally suited to off-line  
applications. The corresponding thresholds for the UC1843 and UC1845 are  
8.4V and 7.6V. The UC1842 and UC1843 can operate to duty cycles  
approaching 100%. A range of zero to 50% is obtained by the UC1844 and  
UC1845 by the addition of an internal toggle flip flop which blanks the output  
off every other clock cycle.
