UCC3803DTR Description

Short technical summary and product information.

The Texas Instruments UCC3803DTR is a versatile DC DC switching controller operating in current mode. It is suitable for applications requiring step-up, step-down, or step-up/step-down voltage conversion.

 

This controller operates within a voltage range of 3.6V to 12V and can function in temperatures from 0°C to 70°C. Key features include a maximum duty cycle of 99%, adjustable and fixed frequency operation up to 1MHz, and various control features such as frequency control, current limiting, and soft start. The device supports multiple topologies including Buck, Boost, Flyback, and Forward Converter.

 

Packaged in an 8-SOIC surface mount configuration, the UCC3803DTR is designed for efficient power management solutions. Its output type is a transistor driver, with a positive output configuration and no synchronous rectifier.

 

This component is part of the UCC280x family, known for high-speed, low-power integrated circuits for switching mode power supplies. It offers internal soft start and leading-edge blanking for improved performance.
