TL1451ACDBR Description

Short technical summary and product information.

The TL1451ACDBR is a versatile DC DC switching controller from Texas Instruments, designed for multiple topologies including buck, boost, and flyback. It operates with a single output phase and provides two transistor driver outputs. The input voltage range spans from 3.6V to 50V, making it suitable for a wide variety of power supply designs.

 

This controller features a frequency control function with an adjustable switching frequency range of 1kHz to 500kHz. It uses a positive output configuration and does not include synchronous rectification or clock synchronization. The device is mounted in a 16-SSOP (Shrink Small Outline Package) with a 5.30mm width, designed for surface mount assembly.

 

Typical applications include power supplies requiring step-up, step-down, or flyback regulation. The operating temperature range is -20°C to 85°C (ambient), allowing use in commercial and industrial environments. The TL1451ACDBR is RoHS3 compliant (unverified) and has a moisture sensitivity level of 1 (unlimited).
