TL1451CN Description

Short technical summary and product information.

The Texas Instruments TL1451CN is a dual pulse-width-modulation (PWM) control circuit integrated onto a single monolithic chip. Primarily designed for power-supply control applications, this IC incorporates an on-chip 2.5-V regulator and two error amplifiers.

 

Key electrical specifications include an operating voltage range from 3.6V to 50V and an adjustable oscillator frequency between 1kHz and 500kHz. The device supports multiple topologies such as Buck, Boost, and Flyback, with a transistor driver output configuration. It features frequency control for precise operation and operates asynchronously.

 

This component is housed in a 16-PDIP package and is designed for through-hole mounting. The operating temperature range is specified from -20°C to 85°C (TA). The TL1451CN is suitable for applications requiring versatile DC/DC conversion.

 

Environmental compliance includes RoHS3 compliance and an MSL of 1. The device is designed for robust performance in various power management systems.
