The UCC2805QDRQ1 from Texas Instruments is an automotive-qualified, low-power BiCMOS current-mode PWM controller. It is designed to support multiple topologies including Boost, Buck, Buck-Boost, Flyback, and Forward converters.
This controller features a wide operating voltage range of 3.6V to 12V and can operate at frequencies up to 1MHz. Key electrical characteristics include a maximum duty cycle of 49%, a typical starting supply current of 100µA, and a typical operating supply current of 500µA. It also provides a 1A totem-pole output and a typical response time of 70ns from current-sense to gate drive.
The device is housed in an 8-SOIC package, suitable for surface mount applications. It operates within a temperature range of -40°C to 125°C (TJ). The UCC2805QDRQ1 is AEC-Q100 qualified, indicating its suitability for automotive applications.
Features such as adjustable switching frequency, current limiting, dead time control, error amplifier, fixed frequency, leading edge blanking, multi-topology support, and soft start are integrated into this controller, making it a versatile solution for power management designs.
