Frequently Asked Questions
What input voltage range does the TPS51215ARUKR support, and how does that affect power-supply design?
The TPS51215ARUKR accepts an input voltage from 3 V to 28 V, with a nominal design point of 12 V. This wide range allows the controller to be used directly from a 12 V bus in desktop or server systems, or from a 5 V bus in embedded applications, simplifying intermediate conversion stages and reducing overall system component count.
How does the 2-bit VID interface on TPS51215ARUKR enable dynamic voltage scaling in processor power stages?
The 2-bit VID interface lets the host processor select among up to 4 pre-programmed output voltage levels at runtime, enabling dynamic voltage scaling without additional analog circuitry. Each VID code change is executed by the D-CAP2 loop, which responds within a few microseconds to keep voltage deviation below the ±50 mV tolerance typical for CPU core rails.
For a -40°C to 125°C industrial design, does the TPS51215ARUKR meet automotive or extended temperature requirements?
Yes. The TPS51215ARUKR is specified for a -40°C to 125°C junction temperature range, matching industrial and many automotive-adjacent applications. The WQFN-20 package provides good thermal conductivity through its exposed pad, and the device is AEC-Q100-style qualification tested, making it suitable for rugged environments with wide ambient temperature swings.
