TL1453CNSR Description

Short technical summary and product information.

The TL1453CNSR from Texas Instruments is a versatile dual-channel pulse-width-modulation (PWM) control circuit designed for power supply applications. It operates with an input voltage range from 3.6V to 40V and can provide an output voltage up to 50V. The device utilizes voltage mode control with a maximum duty cycle of 100% and a configurable frequency range from 1kHz to 500kHz.

 

Key features include internal undervoltage lockout protection, a stable 2.5V reference supply, and variable dead time control. The TL1453CNSR is suitable for multiple topologies including Boost, Buck, Flyback, Forward, and SEPIC configurations. Its uncommitted output transistors offer common-emitter output capability for each controller.

 

This component is available in a 16-SOIC package and is designed for surface mount applications. The operating temperature range is -20°C to 85°C (TA). The TL1453CNSR integrates the necessary functions for constructing two independent PWM control circuits on a single chip, making it an efficient solution for complex power management designs.
