产品概述
The UCC280x-Q1 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 mode power supplies with minimal parts count. These devices have the same pin configuration as the UCx84x family, and also offer the
added features of internal full-cycle soft start and internal leading-edge blanking of the
current-sense input.The UCC280x-Q1 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 UCC2803-Q1 and UCC2805-Q1 fit best into battery-operated systems, while the higher reference and
higher UVLO hysteresis of the UCC2802-Q1 and UCC2804-Q1 make these ideal choices for use in off-line power supplies.The UCC280x-Q1 series is specified for operation from –40°C
to 125°C.
