UCC28C40D Description

Short technical summary and product information.

The Texas Instruments UCC28C40D is a versatile, low-power, current-mode PWM controller suitable for Boost, Buck, Flyback, and Forward converter topologies. It features an adjustable switching frequency up to 1MHz and a maximum duty cycle of 96%.

 

Key electrical characteristics include a wide operating voltage range of 6.6V to 18V, a fast cycle-by-cycle overcurrent limiting response time of 35ns, and a peak driving current of ±1A. The device also offers precise control with a ±1% accurate 2.5V error amplifier reference and features like dead time control and programmable maximum duty cycle.

 

Packaged in an 8-SOIC surface mount configuration, the UCC28C40D operates within a temperature range of -40°C to 105°C (TJ). Its design makes it an enhanced replacement for older UCx84x and UCx84xA family devices, offering improved performance and lower operating current.

 

This controller is ideal for applications requiring efficient power management and precise regulation in a compact form factor.
