Frequently Asked Questions
What is the input voltage range of the TPS53319DQPT?
The TPS53319DQPT supports an input voltage range of 1.5V to 22V for the power stage, with a separate bias supply (VDD) of 4.5V to 25V. The nominal operating input voltage is 12V, making it well-suited for standard server and industrial 12V power rails.
What output voltage and current can the TPS53319DQPT deliver?
The TPS53319DQPT provides an adjustable output voltage from 0.6V to 5.5V and is rated for up to 14A continuous output current. This makes it suitable for powering processors, FPGAs, and memory modules that require precisely regulated low voltages from a 12V bus.
What is Eco-Mode and when does the TPS53319DQPT activate it?
Eco-Mode is a pulse-skipping light-load efficiency technique integrated in the TPS53319DQPT. At light loads, the converter automatically reduces switching frequency to minimize switching losses and quiescent current, improving system efficiency in standby or low-demand operating conditions.
What package does the TPS53319DQPT come in, and what are its dimensions?
The TPS53319DQPT uses a 22-pin Small Outline No-lead (SON/QFN-style) package coded JESD-30 R-PDSO-N22. This compact, thermally enhanced footprint facilitates efficient heat dissipation and is optimized for high-density PCB layouts in space-constrained applications.
Is the TPS53319DQPT RoHS compliant and lead-free?
Yes, the TPS53319DQPT is lead-free and RoHS compliant, as indicated by its Pbfree Code: Yes and JESD-609 Code: e3. It meets international environmental regulations for hazardous substances, making it suitable for consumer electronics and industrial designs requiring green compliance.
