What are the key features of TPS563211DRLR?

  • Current-mode PWM synchronous buck topology for high efficiency across 4.2V to 18V input range
  • 3A continuous output current capability in a compact R-PDSO-F8 (SOT-23-8) package
  • 12V nominal input targets industrial 12V rail and automotive 12V bus applications directly
  • Introduced in 2020 with 15-year estimated EOL for long lifecycle industrial and communications designs

What is TPS563211DRLR used for?

TPS563211DRLR is ideal for point-of-load regulation on 12V industrial power buses, converting to lower voltages for microcontrollers, FPGAs, and peripheral ICs. It suits telecom infrastructure, networking equipment, and factory automation controllers that require efficient 12V step-down conversion. The compact SOT-23-8 footprint also benefits space-constrained consumer electronics requiring a reliable 18V-capable buck regulator.

Frequently Asked Questions

What input voltage range does TPS563211DRLR support and what is its nominal design point?

TPS563211DRLR accepts input voltages from 4.2V minimum to 18V maximum, with a 12V nominal operating point. This wide 4.2V to 18V range covers standard 12V industrial rails, 5V USB power, and input voltages that can surge above 12V in automotive or industrial environments.

How much output current can TPS563211DRLR deliver continuously?

TPS563211DRLR is rated for 3A continuous output current using its synchronous buck topology. The current-mode PWM control ensures cycle-by-cycle current limiting, protecting the IC and load during transient overload events while maintaining stable regulation at the full 3A level.

Which package does TPS563211DRLR use and how does it affect PCB layout?

TPS563211DRLR comes in the R-PDSO-F8 package, an 8-pin SOT-23 flat-lead format with a very small 2.9mm x 1.6mm footprint. This compact 8-pin package simplifies high-density PCB layouts, allowing the regulator to fit near the load with short power traces and reduced parasitic inductance.

When is TPS563211DRLR preferred over larger DC-DC buck regulators for 12V step-down designs?

TPS563211DRLR is preferred when output current requirements are at or below 3A and PCB space is limited, avoiding the larger footprint of higher-current converters. Its 2020 introduction with a 15-year estimated EOL also makes it attractive for new industrial and communications designs that require long-term component availability.
