The Texas Instruments UCC2803QDRQ1 is a low-power BiCMOS current-mode PWM controller designed for automotive applications. It features a wide operating voltage range from 3.6V to 12V and supports multiple topologies including Boost, Flyback, and Forward converters.
This controller operates at frequencies up to 1MHz, with a maximum duty cycle of 99%. Key electrical features include adjustable switching frequency, current limiting, dead time control, an error amplifier, and internal soft start for both normal and fault conditions. It also incorporates internal leading-edge blanking of the current sense signal.
The UCC2803QDRQ1 is housed in an 8-SOIC package, suitable for surface mount applications. It is AEC-Q100 qualified with a temperature grade of 1 (-40°C to 125°C TA), HBM classification level 2, and CDM classification level C5, making it robust for automotive environments. Documentation is available to aid in functional safety system design.
With a typical starting supply current of 100µA and operating current of 500µA, this controller is designed for efficiency. It offers a 1A totem-pole output and a fast response time from current-sense to gate drive output.
