Applications and Design Value
The TLM966411F-101 is intended for high-current voltage regulator designs where rapid transient response and power density are critical. Its main applications include:
AI server accelerator cards
GPU and CPU core power rails
FPGA power supplies
High-performance computing systems
Network switches and data-center equipment
Multiphase TLVR power converters
The low primary DCR helps limit conduction losses, while the TLVR structure improves current sharing and transient response in multiphase regulators. This can reduce the output capacitance and PCB area required compared with a conventional VRM, although the final result depends on the controller, phase count, switching frequency and system layout.

Frequently Asked Questions
Is the TLM966411F-101 rated for 75A?
Yes. Its primary winding has a rated current of 75A. Actual allowable current depends on PCB design, airflow, ambient temperature and acceptable temperature rise.
What is the saturation current of TLM966411F-101?
The specified saturation current is 98A at 25°C, 83A at 100°C and 78A at 125°C. Designers should use the value corresponding to the expected operating temperature.
Where is TLM966411F-101 typically used?
It is mainly used in TLVR power supplies for AI processors, GPUs, CPUs, FPGAs, server motherboards and high-performance network switches.
How is a TLVR inductor different from a conventional power inductor?
A TLVR trans-inductor uses a coupled four-terminal structure within a multiphase regulator. It is designed to improve transient response and current balancing when processor loads change rapidly.
Can another 100nH inductor directly replace TLM966411F-101?
Not necessarily. A replacement must be checked for DCR, saturation current, rated current, coupling characteristics, pin configuration, winding direction, dimensions and thermal performance. Matching only the 100nH inductance value is insufficient.
