UCC2803PWTR Description

Short technical summary and product information.

The Texas Instruments UCC2803PWTR is a low-power BiCMOS current-mode PWM controller. It is suitable for off-line and DC-to-DC fixed frequency switching mode power supplies with minimal parts count.

 

Key electrical specifications include an operating voltage range of 3.6V to 12V and a maximum duty cycle of 99%. The controller operates at a frequency of 31kHz and supports multiple topologies such as Boost, Flyback, and Forward converters. It features adjustable switching frequency, current limiting, dead time control, an error amplifier, fixed frequency operation, leading-edge blanking, multi-topology support, and soft start.

 

This device is available in an 8-TSSOP package and is designed for surface mount applications. It offers a typical starting supply current of 100µA and a typical operating supply current of 500µA. The operating temperature range is -40°C to 85°C (TA).

 

The UCC2803PWTR is part of the UCC280x family, offering integrated control and drive components for efficient power supply designs. Its features make it suitable for battery-operated applications.
