Texas Instruments UCC2800/2801/2802/2803/2804/2805-Q1 Data Sheet
The UCC2800/1/2/3/4/5 family are high‑speed, low‑power integrated circuits designed for off‑line and dc‑to‑dc fixed‑frequency current‑mode switching power supplies. They share the same pinout as the UC3842 family and add internal full‑cycle soft‑start and leading‑edge blanking of the current‑sense input. The Q1 series is qualified for automotive temperature ranges (‑40 °C to 125 °C) and meets AEC‑Q100 stress‑test requirements.
The document provides ordering information, absolute maximum ratings, detailed electrical characteristics, terminal descriptions, and packaging data. It includes tables of maximum duty cycle, reference voltage, turn‑on/off thresholds, and other key parameters for each part number in the family.
