DESCRIPTION
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.
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.
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 –55
oC to +125oC,
the UCC280x series is specified for operation from –40
oCto+85oC, and
the UCC380x series is specified for operation from 0
oCto+70oC.
