TL1451ACPW Description

Short technical summary and product information.

The TL1451ACPW from Texas Instruments is a dual channel pulse-width-modulation (PWM) control circuit designed for DC/DC conversion applications. It supports multiple topologies including Buck, Boost, and Flyback configurations, offering flexibility for various power supply designs.

 

This controller operates with a wide input voltage range from 3.6V to 50V, making it suitable for a broad spectrum of applications. It features a maximum output voltage of 50V and a minimum of 1V. The device operates in voltage mode with nonsynchronous rectification and can be synchronized. Its frequency control feature allows for operation between 1kHz and 500kHz, with a maximum duty cycle of 100%.

 

The TL1451ACPW is available in a 16-TSSOP package and is designed for surface mount applications. It has an operating temperature range of -20°C to 85°C (TA). The typical quiescent current is 0.0017A.

 

Key features include internal undervoltage lockout protection, internal short-circuit protection, and a stable 2.5-V reference supply. The device is qualified to automotive standards and is available in Q-Temp Automotive HighRel.
