UCC28C44DGKR Description

Short technical summary and product information.

The Texas Instruments UCC28C44DGKR is an active industrial, low-power current-mode PWM controller. It is designed for applications requiring efficient power management, supporting topologies such as Boost, Flyback, and Forward converters.

 

This controller features an adjustable switching frequency up to 1MHz and a maximum duty cycle of 48%. It offers essential control features like frequency control and operates within a voltage range of 9V to 18V. The device is housed in an 8-VSSOP package, suitable for surface mount applications.

 

Key electrical characteristics include a positive output configuration and a transistor driver output type. The operating temperature range is -40°C to 105°C (TJ). This component is an enhanced replacement for the UCx84x and UCx84xA family, offering improved performance and efficiency.

 

The UCC28C44DGKR is suitable for designs where space is a constraint due to its compact 8-VSSOP package. Its robust features make it a versatile choice for power supply designs.
