UC2842ADTR Description

Short technical summary and product information.

The UC2842ADTR from Texas Instruments is a versatile current mode PWM controller suitable for a wide range of off-line and DC-DC converter applications. It supports multiple topologies including Boost, Buck, Flyback, and Forward configurations.

 

This controller operates within a voltage range of 10V to 30V and can achieve frequencies up to 500kHz. Key features include a maximum duty cycle of 96%, frequency control, and a transistor driver output type. It is designed for surface mount installation in a 14-SOIC package.

 

Enhanced features such as low start-up current (<0.5mA), trimmed oscillator discharge current (8.3mA), and undervoltage lockout (UVLO) with hysteresis (16V/10V) contribute to its robust performance. The output stage can sink at least 10mA during UVLO conditions when VCC is over 5V.
