What are the key features of TPS59124RGER?
- Multi-phase synchronous buck controller supporting up to 4 phases for high-current loads exceeding 100A with interleaved switching to reduce input ripple
- Precision 0.6V internal reference voltage with tight regulation accuracy for low-voltage CPU and FPGA core power rails
- Wide input voltage range and adaptive voltage positioning (AVP) support for server and high-performance computing power delivery networks
What is TPS59124RGER used for?
The TPS59124RGER is designed for server, workstation, and high-performance computing power delivery where multi-phase buck regulation is required to supply CPU, GPU, or FPGA core voltages efficiently at high currents. Its multi-phase architecture reduces filter size and improves transient response, making it appropriate for telecom and networking equipment power stages. The device is also used in advanced graphics card and AI accelerator board designs requiring precise low-voltage regulation with fast load-step recovery.

Frequently Asked Questions
How many phases can the TPS59124RGER control and what current levels does this support?
The TPS59124RGER supports up to 4-phase synchronous buck operation, allowing power delivery exceeding 100A to high-current processor and FPGA core rails by distributing switching current across multiple phases to reduce thermal stress and inductor size.
What reference voltage does the TPS59124RGER use for output regulation accuracy?
The TPS59124RGER uses an internal 0.6V precision reference for output voltage regulation, enabling tight control of sub-1V core supply rails required by modern CPUs and FPGAs while maintaining regulation accuracy across load and temperature variations.
In which package is the TPS59124RGER supplied and how does it affect thermal management on a server motherboard?
The TPS59124RGER is supplied in a 24-pin QFN (RGE) package with an exposed thermal pad, providing low thermal resistance to the PCB. This allows effective heat dissipation in high-density server motherboard layouts where airflow may be limited around the power delivery section.
When is TPS59124RGER a better fit than a single-phase controller for an FPGA core power design?
For FPGA core currents above 30A, the TPS59124RGER multi-phase approach reduces per-phase inductor current to under 10A per phase at 4 phases, lowering inductor DCR losses, reducing output capacitance by roughly 4x, and improving load transient response compared to a single-phase controller solution.
