DESCRIPTION
The UCC3813-0/-1/-2/-3/-4/-5 family of high-speed, low-power inte-
grated circuits 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 UC3842/3/4/5
family, and also offer the added features of internal full-cycle soft start
and internal leading-edge blanking of the current-sense input.
The UCC3813-0/-1/-2/-3/-4/-5 family offers a variety of package options,
temperature range options, choice of maximum duty cycle, and choice
of critical voltage levels. Lower reference parts such as the UCC3813-3
and UCC3813-5 fit best into battery operated systems, while the higher
reference and the higher UVLO hysteresis of the UCC3813-2 and
UCC3813-4 make these ideal choices for use in off-line power supplies.
The UCC2813-x series is specified for operation from –40°C to +85°C
and the UCC3813-x series is specified for operation from 0°C to +70°C.
