description
The UCC2813-0/-1/-2/-3/-4/-5 family of high-speed, low-power integrated 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 UC2842/3/4/5 family and also offer the added features
of internal full-cycle soft start and internal leading-edge blanking of the current-sense input.
The UCC2813-0/-1/-2/-3/-4/-5 family offers choice of maximum duty cycle and critical voltage levels. Lower
reference parts such as the UCC2813-3 and UCC2813-5 fit best into battery operated systems, while the higher
reference and the higher UVLO hysteresis of the UCC2813-2 and UCC2813-4 make these ideal choices for use
in off-line power supplies.
The UCC2813-xQ-Q1 series is specified for the automotive temperature range of 40
_C to 125_C.
