TL3844BD-8 Description

Short technical summary and product information.

The TL3844BD-8 is a high-performance current-mode Pulse Width Modulation (PWM) controller from Texas Instruments, part of the TLx84xB series. This integrated circuit 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 up to 500kHz. The device features a maximum duty cycle of 48% and offers frequency control as a primary feature. It operates within a temperature range of 0°C to 70°C.

 

The controller is suitable for various applications, including switching regulators of any polarity and transformer-coupled DC/DC converters. It is packaged in an 8-SOIC (Surface Mount) package, measuring 8-SOIC (0.154", 3.90mm Width).

 

This part is obsolete and no longer in production. An alternate part, TL3844BDR-8, is available with upgraded functionality.
