TL3844DR-8 Description

Short technical summary and product information.

The TL3844DR-8 from Texas Instruments is an active component in the DC DC Switching Controllers category. This current mode PWM controller is optimized for off-line and DC-to-DC converters, offering features such as adjustable switching frequency, current limiting, and an error amplifier. It supports Boost, Flyback, and Forward topologies.

 

This device operates within a voltage range of 10V to 30V and has a maximum duty cycle of 48%. The operating temperature range is from 0°C to 70°C. It is housed in an 8-SOIC package and is designed for surface mount applications.

 

Key internal circuits include undervoltage lockout (UVLO) with hysteresis, double-pulse suppression, and a high-current totem-pole output. The TL3844 series is designed to be interchangeable with UC2842 and UC3842 series controllers, providing a flexible solution for power management designs.
