UC2843D8TRG4 Description

Short technical summary and product information.

The UC2843D8TRG4 from Texas Instruments is a versatile current mode PWM controller. It is optimized for off-line and DC-to-DC converters, supporting topologies such as Boost, Buck, Buck-Boost, Flyback, and Forward.

 

This controller features an operating voltage range of 12V to 28V and can operate at frequencies up to 500kHz. The maximum duty cycle is 97%. It includes control features like frequency control and an error amplifier. The device is housed in an 8-SOIC package and is designed for surface mounting.

 

Key electrical characteristics include a single output with a transistor driver output type and positive, isolation capable configuration. It is not a synchronous rectifier and does not feature clock synchronization. The operating temperature range is -40°C to 85°C.

 

This component is suitable for applications requiring efficient power conversion and precise control. Its surface mount package and wide operating conditions make it adaptable to various design requirements.
