UC2842DTR Description

Short technical summary and product information.

The UC2842DTR from Texas Instruments is a current mode PWM controller IC suitable for off-line and DC-to-DC converters. It supports various topologies including Boost, Buck, Buck-Boost, Flyback, and Forward configurations.

 

This controller operates with an input voltage range of 12V to 28V and can achieve switching frequencies up to 500kHz. The maximum duty cycle is rated at 97%. It features adjustable switching frequency, current limiting, dead time control, and an error amplifier. The operating temperature range is -40°C to 85°C.

 

The UC2842DTR is available in a 14-SOIC package and is designed for surface mount applications. Its output type is a transistor driver, and it is not a synchronous rectifier. The control features include frequency control, making it a versatile component for power management designs.

 

Key internal circuits include undervoltage lockout (UVLO) with hysteresis, a precision reference, latched operation logic, a pulse-width modulation (PWM) comparator for current-limit control, and a high-current totem-pole output stage.
