Frequently Asked Questions
What is the input voltage range supported by TPS5401DGQR?
TPS5401DGQR accepts input voltages from 3.5V to 42V, making it suitable for 12V and 24V industrial bus applications. This wide range covers automotive, telecom, and factory automation power rails with a single compact device.
How much output current can TPS5401DGQR deliver, and what switching frequency does it use?
TPS5401DGQR delivers up to 0.5A continuous output current. It operates with adjustable switching frequency, typically around 200 kHz to 500 kHz, allowing designers to optimize between efficiency and filter component size in 3.5V to 42V step-down applications.
Which industrial or automotive applications benefit most from using TPS5401DGQR?
Applications such as 24V PLC backplanes, automotive body electronics, and distributed 12V supply rails benefit from TPS5401DGQR. Its 42V input tolerance handles load-dump transients up to 40V, and the 0.5A output supports logic rails powering microcontrollers and communication ICs.
When would TPS5401DGQR be preferred over a larger Texas Instruments SWIFT regulator?
TPS5401DGQR is preferred when the load current is 0.5A or below and board space is at a premium, since the MSOP-10 package occupies less than 9 mm² of PCB area. Higher-current SWIFT regulators add unnecessary cost and size for light-load sub-systems below 0.5A.
