UC2842D8 Description

Short technical summary and product information.

The UC2842D8 from Texas Instruments is a current mode Pulse Width Modulation (PWM) controller IC. It is optimized for off-line and DC-to-DC converter applications, requiring a minimal number of external components for implementation.

 

This controller supports a wide input voltage range of 12V to 28V and operates at frequencies up to 500kHz. It features a maximum duty cycle of 97% and offers features such as automatic feedforward compensation, pulse-by-pulse current limiting, and undervoltage lockout with hysteresis.

 

The UC2842D8 is housed in an 8-SOIC package and is designed for surface mount applications. Its operating temperature range is -40°C to 85°C.

 

Key functionalities include Step-Up, Step-Down, and Step-Up/Step-Down topologies, with an output type of Transistor Driver. It is not a synchronous rectifier and does not support clock synchronization.
