The Texas Instruments UCC28C40DGKR is a high-performance, low-power current-mode PWM controller. It is designed for applications requiring efficient power conversion, supporting topologies such as Boost, Flyback, and Forward converters.
Key electrical specifications include an operating voltage range of 6.6V to 18V and an operating frequency of up to 1MHz. The controller features a maximum duty cycle of 96% (from DB) and 100% (from MP), fast cycle-by-cycle overcurrent limiting with a 35ns response time, and a peak driving current of ±1A. It also includes a precise 2.5V error amplifier reference with ±1% accuracy.
Packaged in an 8-VSSOP or 8-TSSOP/MSOP, the UCC28C40DGKR is suitable for surface mount applications. It operates within a temperature range of -40°C to 105°C (TJ). This controller is an enhanced replacement for the UCx84x and UCx84xA families, offering improved performance and lower operating current.
This device is well-suited for various industrial and power supply designs where precise control and efficient operation are critical. Its features facilitate the design of compact and reliable power solutions.
