Frequently Asked Questions

What is the input voltage range of the TPS549A20RVET?

The TPS549A20RVET accepts an input voltage range of 4.5V to 20V, with a nominal operating voltage of 12V. This wide range makes it compatible with standard 12V bus architectures used in servers, networking, and industrial systems.

What control method does the TPS549A20RVET use?

The TPS549A20RVET employs current-mode pulse width modulation (PWM) control. This technique provides inherent cycle-by-cycle current limiting, improved transient response, and easier loop compensation compared to voltage-mode control.

What package does the TPS549A20RVET come in?

The TPS549A20RVET is housed in a 28-pin Quad Flat No-Lead (QFN) package, designated JESD-30 code R-PQCC-N28. The leadless QFN package offers excellent thermal performance and a small PCB footprint suitable for high-density board designs.

What are typical applications for the TPS549A20RVET?

Typical applications include point-of-load power conversion for FPGAs, ASICs, and DDR memory in data center servers, networking switches, telecom equipment, and industrial control systems requiring high-current, efficient step-down regulation from a 12V bus.
