Frequently Asked Questions
What is the input voltage range of the TPS54628DDAR?
The TPS54628DDAR operates from a 4.5V to 18V input voltage range, with a nominal input of 12V. This wide range makes it suitable for 5V and 12V bus power applications in industrial and communications systems.
What output current can the TPS54628DDAR deliver?
The TPS54628DDAR supports up to 6A continuous output current. It uses integrated high- and low-side MOSFETs in a synchronous topology to achieve high efficiency at heavy loads while minimizing external component count.
What is Eco-mode and how does it benefit the TPS54628DDAR design?
Eco-mode is a light-load efficiency feature that reduces switching frequency and quiescent current when output load is low. This improves overall system efficiency in applications with variable loads, such as battery-backed systems or standby power stages.
What package does the TPS54628DDAR come in, and is it RoHS compliant?
The TPS54628DDAR is available in an 8-pin Small Outline (SO-8 / R-PDSO-G8) surface-mount package. It is lead-free (Pb-free code: Yes, JESD-609 code: e4), making it fully RoHS compliant for use in modern electronics manufacturing.
