LM20143MHX/NOPB Description

Short technical summary and product information.

The LM20143MHX/NOPB from Texas Instruments is a high-performance, adjustable frequency synchronous buck regulator. It is designed to provide efficient power conversion for a variety of applications, delivering up to 3A of output current.

 

Key electrical specifications include an input voltage range of 2.95V to 5.5V and an adjustable output voltage down to 0.8V. The device features a switching frequency that can be adjusted from 500 kHz to 1.5 MHz, allowing for optimization of performance and component size. With a peak efficiency of 97% and low quiescent current, it is suitable for power-sensitive designs.

 

This regulator incorporates several features for enhanced functionality and protection, such as Enable, Power Good, Pre-Bias Start-Up, Synchronous Rectification, and Tracking. It also includes integrated Overvoltage Protection (OVP), Undervoltage Lockout (UVLO), Power Good indication, and Thermal Shutdown.

 

The LM20143MHX/NOPB is supplied in a 16-HTSSOP package, designed for surface mounting. Its operating temperature range is -40°C to 125°C (TJ).
