Low-Power BiCMOS Current-Mode PWM  
FEATURES  
DESCRIPTION  
100µA Typical Starting Supply Current  
The UCC1800/1/2/3/4/5 family of high-speed, low-power integrated cir-  
cuits contain all of the control and drive components required for off-line  
and DC-to-DC fixed frequency current-mode switching power supplies  
with minimal parts count.  
500µA Typical Operating Supply  
Current  
Operation to 1MHz  
Internal Soft Start  
These devices have the same pin configuration as the UC1842/3/4/5  
family, and also offer the added features of internal full-cycle soft start  
and internal leading-edge blanking of the current-sense input.  
Internal Fault Soft Start  
The UCC1800/1/2/3/4/5 family offers a variety of package options, tem-  
perature range options, choice of maximum duty cycle, and choice of  
critical voltage levels. Lower reference parts such as the UCC1803 and  
UCC1805 fit best into battery operated systems, while the higher refer-  
ence and the higher UVLO hysteresis of the UCC1802 and UCC1804  
make these ideal choices for use in off-line power supplies.  
The UCC180x series is specified for operation from –55oC to +125oC,  
the UCC280x series is specified for operation from –40oC to +85oC, and  
the UCC380x series is specified for operation from 0oC to +70oC.  
Internal Leading-Edge Blanking of the  
Current Sense Signal  
1 Amp Totem-Pole Output  
70ns Typical Response from  
Current-Sense to Gate Drive Output  
1.5% Tolerance Voltage Reference
