UCC2804-Q1
description
The UCC2800/1/2/3/4/5 family of high-speed, low-power integrated circuits contain all of the control and drive ponents 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 UCC2800/1/2/3/4/5 family offers choice of maximum duty cycle and critical voltage levels. Lower reference parts such as the UCC2803 and UCC2805 fit best into battery operated systems, while the higher reference and the higher UVLO hysteresis of the UCC2802 and UCC2804 make these ideal choices for use in off-line power supplies.
The UCC280x QDRQ1 series is specified for the automotive temperature range of
- 40_C to 125_C, and qualified in accordance with AEC-Q100 stress test qualification for integrated circuits.
