What are the key features of TPS53319DQPR?
- 14 A peak output current with PWM control enables high-efficiency step-down regulation for CPU and FPGA core supplies
- Wide 1.5 V to 22 V input voltage range supports a broad set of power architectures from 5 V to 19 V bus designs
- Compact 22-pin WSON package (JESD-30 R-PDSO-N22) minimizes PCB footprint for dense server and telecom boards
- RoHS compliant lead-free construction (JESD-609 e4) with 15+ years estimated end-of-life for long-lifecycle industrial deployments
What is TPS53319DQPR used for?
The TPS53319DQPR is optimized for point-of-load voltage regulation in servers, networking equipment, and high-performance computing boards that require 14 A step-down conversion from 12 V bus rails. Its wide input range and PWM control also make it a strong candidate for industrial automation controllers and telecom infrastructure power supplies where efficiency and thermal performance across a 1.5 V to 22 V input are critical.

Frequently Asked Questions
What output current can TPS53319DQPR supply, and what control technique does it use?
The TPS53319DQPR supports up to 14 A of output current using pulse-width modulation (PWM) control, making it capable of powering high-current digital loads such as FPGAs, DSPs, and multi-core processors from a 12 V nominal bus.
What is the input voltage range of TPS53319DQPR, and which bus architectures does it support?
TPS53319DQPR operates from 1.5 V to 22 V input voltage, with a 12 V nominal input, covering standard 5 V, 12 V, and 19 V bus architectures used in server blades, desktop platforms, and industrial controllers requiring a single step-down regulator.
How does TPS53319DQPR's WSON package compare to a SOIC for high-density board layouts?
The 22-pin WSON package (R-PDSO-N22) offers a significantly smaller footprint than a typical SOIC-8 or SOIC-16, enabling tighter component placement on dense PCBs with smaller thermal pad area. This is advantageous in server blade designs where every mm² of board space matters.
What estimated product lifecycle does TPS53319DQPR carry, and is it suitable for long-term industrial designs?
The TPS53319DQPR carries a YTEOL of 15 years, making it a sound choice for long-lifecycle industrial, medical, and telecom equipment programs where 10+ year production continuity is required. Its RoHS e4 lead-free compliance further eases global regulatory approval.
