TPS53353DQPR
Brand: Texas Instruments
The TPS53353DQPR steps the copper-clip LSON synchronous buck family up to 20 A — the highest current in this pair — while keeping the same 1.5 V to 22 V power input and 4.5 V to 25 V bias supply as the TPS53319. It targets the most demanding FPGA, ASIC and processor core-voltage rails in server and networking equipment.

Power Features & Applications
- 20 A output current tops the TPS53319 sibling for the highest-current single-device solution in this pair
- Copper-clip LSON package construction lowers resistance and improves thermal transfer versus bond wires
- Separate bias supply (4.5–25 V) and power rail (1.5–22 V) inputs support flexible system architectures
- Synchronous rectification with integrated MOSFETs maximizes conversion efficiency at high current
- Adjustable output voltage fits a wide range of digital-load core voltages
- -40°C to +85°C rating suits server and networking equipment enclosures
