for applications ranging from off-line power  
supplies to battery operated portable equipment.  
Dual high-current, MOSFET driving outputs and a  
fast current sense loop further enhance device  
versatility.

All the benefits of current mode control including  
simpler loop closing, voltage feed-forward,  
parallelability with current sharing, pulse-by-pulse  
current limiting, and push/pull symmetry  
correction are readily achievable with the  
UCC3806 series.  
Easier Parallelability  
Improved Benefits of Current Mode Control  
DESCRIPTION  
These devices are available in multiple package  
options for both through-hole and surface mount  
applications; and in commercial, industrial, and  
military temperature ranges.  
The UCC3806 family of BiCMOS PWM controllers  
offers exceptionally improved performance with a  
familiar architecture. With the same block diagram  
and pinout of the popular UC3846 series, the  
UCC3806 line features increased switching  
frequency capability while greatly reducing the  
bias current used within the device. With a typical  
startup current of 50 µA and a well defined voltage  
threshold for turn-on, these devices are favored  
The UCC3806 is specified for operation from  
−55°C to 125°C, the UCC2806 is specified for  
operation from −40°C to 85°C, and the UCC3806  
is specified for operation from 0°C to 70°C.
