What are the key features of TPS51211DSCR?
- Voltage-mode PWM control for a single synchronous step-down stage, operating from 3 V to 28 V input for broad power supply compatibility
- Adjustable output voltage range of 0.7 V to 2.6 V covers modern CPU core, memory, and chipset rail requirements
- Compact 10-pin WSON (S-PDSO-N10) package minimizes PCB footprint in densely packed server, notebook, and industrial power designs
What is TPS51211DSCR used for?
The TPS51211DSCR is designed for notebook and desktop CPU core voltage regulators where input rails of 3 V to 28 V must be efficiently converted to sub-1 V or sub-2.6 V processor supplies. It is equally suited to DDR memory power stages and chipset rails in server motherboards demanding precise voltage-mode control with fast transient response. Industrial embedded systems that require a compact, adjustable synchronous buck controller for point-of-load conversion also benefit from this device.

Frequently Asked Questions
What is the adjustable output voltage range of TPS51211DSCR, and which processor rails does it cover?
The TPS51211DSCR supports an adjustable output voltage range of 0.7 V to 2.6 V, which spans common CPU core voltages below 1 V, DDR memory rails at 1.2 V to 1.8 V, and chipset I/O rails up to 2.5 V. This versatility makes it a single-controller solution for multiple power-hungry loads on the same motherboard or embedded platform operating from a 3 V to 28 V input.
How does TPS51211DSCR perform in a 12 V input, sub-1 V CPU core voltage design compared to fixed-voltage controllers?
With a 12 V nominal input within its 3 V to 28 V range and an adjustable 0.7 V to 2.6 V output, TPS51211DSCR provides significantly more flexibility than fixed-voltage controllers, which require component changes to retarget the output. Its voltage-mode PWM architecture ensures stable regulation at the tight tolerances required by modern processor VR specifications, and the 10-pin WSON package keeps the solution area small enough for compact laptop and mini-PC motherboards.
Under what procurement scenario should a designer consider TPS51211DSCR over a multi-phase controller for a mid-range server?
For a mid-range server rail drawing moderate current where a single-phase synchronous buck is sufficient, TPS51211DSCR reduces bill-of-materials cost and complexity compared to multi-phase controllers that require additional driver ICs and more power stages. The 3 V to 28 V input range accommodates 12 V and 24 V bus architectures, and the 10-pin WSON package leaves room on the PCB for other components, making it a cost-effective choice when peak load current stays within a single-phase design budget.
