TPS54040ADGQR Description

Short technical summary and product information.

The Texas Instruments TPS54040ADGQR is an integrated circuit designed for power management applications. This device functions as a step-down DC/DC converter, capable of delivering up to 0.5A of output current.

 

Key electrical specifications include a wide input voltage range from 3.5V to 42V, with an adjustable output voltage ranging from 0.8V to 39V. The converter operates with a switching frequency adjustable between 100kHz and 2.5MHz. It features a typical quiescent current of 116µA and a shutdown current of 1.3µA, contributing to its efficiency, especially at light loads through its Pulse Skipping Eco-Mode.

 

The TPS54040ADGQR is housed in a 10-pin HVSSOP package, also referred to as 10-MSOP. This surface-mount package has dimensions of 3 mm x 4.9 mm (14.7 mm²). The operating temperature range for this component is -40°C to 150°C (TJ). Additional features include adjustable UVLO, power good output, and frequency synchronization capabilities.
