The TPS54561DPRR is a high-efficiency synchronous buck converter from Texas Instruments, delivering 5A continuous output current across an ultra-wide 4.5V to 60V input range. This WSON-10 packaged regulator achieves up to 95% efficiency with Eco-mode operation, making it ideal for 24V industrial power systems, automotive electronics, and FPGA power supplies — exactly the part for any rail that needs strong efficiency margin from a wide DC bus.
Current-mode control with external compensation delivers stable loop response across load steps, and the adjustable switching frequency (100kHz-2.5MHz) lets designers trade off noise, efficiency, and external component size. The compact 4×4mm package with thermal pad handles the thermal load of 5A continuous output without forced air, and integrated protections — thermal shutdown, UVLO, cycle-by-cycle current limiting — keep the regulator safe through abnormal load and supply events.
5A Output Current with Adjustable 0.8V-59V & Thermal Protection
Current-mode control with external compensation — predictable loop stability across operating conditions.
Adjustable frequency (100kHz-2.5MHz) — trade off noise, efficiency, and external component sizing.
Integrated protections — thermal shutdown, UVLO, and cycle-by-cycle current limiting.
Space-saving design — 4×4mm WSON-10 package with thermal pad for compact PCB layouts.
Power-good signal and soft-start — clean power sequencing for downstream digital and analog loads.
Where the TPS54561DPRR Fits
The wide input range and 5A output capacity put this part on 24V and 48V industrial rails as the workhorse step-down to lower core and logic voltages. Common applications: routers and PLCs running off 24V backplanes, motor-drive auxiliary supplies, FPGA power trees with multiple downstream LDOs, and automotive 12V/24V systems where a single rugged buck handles both nominal and load-dump conditions. The -40°C to +125°C industrial temperature envelope covers harsh deployment scenarios without de-rating.
