TL3844BD Description

Short technical summary and product information.

The TL3844BD from Texas Instruments is a high-performance current-mode Pulse Width Modulation (PWM) controller IC. It is designed to facilitate the implementation of off-line or DC-to-DC fixed-frequency current-mode control schemes with minimal external components.

 

Key electrical specifications include an operating voltage range of 10V to 30V and a maximum operating frequency of 500kHz. The device supports various topologies such as Boost, Flyback, and Forward converters. It features a maximum duty cycle of 48% and operates with a positive output configuration. The controller includes frequency control features.

 

This component is suitable for applications requiring switching regulators of any polarity or transformer-coupled DC/DC converters. It operates within a temperature range of 0°C to 70°C. The TL3844BD is supplied in a 14-SOIC surface mount package, offering a compact solution for power management designs.
