TL1451ACNSR Description

Short technical summary and product information.

The TL1451ACNSR from Texas Instruments is a dual-channel pulse-width-modulation (PWM) control circuit designed for DC/DC conversion applications. It offers a wide input voltage range, supporting from 3.6V up to 50V, making it versatile for various power supply designs.

 

This controller supports multiple topologies including Buck, Boost, and Flyback configurations. It features a non-synchronous rectification output and operates with a frequency control feature, adjustable from 1kHz to 500kHz. The device provides two outputs and one output phase, with the output configuration being positive.

 

Packaged in a 16-SOIC surface mount package, the TL1451ACNSR is suitable for applications requiring efficient power management. Its operating temperature range is specified as -20°C to 85°C (TA) according to the database, though the manufacturer page indicates a wider range of -40°C to 125°C.

 

Key electrical characteristics include a maximum duty cycle of 100% and a typical quiescent current of 0.0017A. The device also includes internal undervoltage lockout protection and internal short-circuit protection, contributing to robust power system designs.
