UCC28C44DGK Description

Short technical summary and product information.

The Texas Instruments UCC28C44DGK is a high-performance, low-power current-mode Pulse Width Modulation (PWM) controller. It is designed for applications requiring efficient power conversion, supporting topologies such as Boost, Buck, Flyback, and Forward converters.

 

Key electrical specifications include an operating voltage range of 9V to 18V, a maximum frequency of 1MHz, and a maximum duty cycle of 48%. The device offers fast, cycle-by-cycle overcurrent limiting with a response time of 35ns and provides a peak driving current of ±1A. It also features a precise 2.5V error amplifier reference with ±1% accuracy.

 

This controller is housed in an 8-VSSOP package, suitable for surface mounting. The operating temperature range is -40°C to 105°C (TJ). It is an enhanced replacement for the UCx84x and UCx84xA families, offering improved performance and lower operating current.

 

The UCC28C44DGK is suitable for a wide range of industrial power supply designs where efficient and reliable control is essential.
