Coupled Ferrite Design
HCMD: Optimized for TLVR Topology
The High Current Multiphase Dual Inductor is specifically designed for use in TLVR (Trans Inductor Voltage Regulator) topology, featuring a coupled ferrite design. This advanced configuration is ideal for high-power processors, offering a high coupling factor and the ability to handle high currents over short periods.
Key Components and Features:
- MnZn Core Material: The HCMD utilizes MnZn (Manganese-Zinc) core material known for its high permeability, ensuring efficient magnetic performance.
- Airgap: An airgap is incorporated to control and modify the inductance, providing precise tuning capabilities.
- External Flat Wire: The external flat wire is designed without isolation, optimizing it for high current applications and low RDC values
- Internal Flat Wire: The internal flat wire comes with isolation, ensuring safety and reliability in high-power environments.
Each component of the HCMD is meticulously crafted to deliver a comprehensive solution for high-power processing needs, ensuring optimal performance and reliability.
TLVR Topology
The trans-inductor voltage regulator (TLVR) topology is a further development of the multiphase buck regulator. It offers fast transient response in applications where sudden load changes occur as well as power density and solution cost.
The primary side of each coupled inductor (HCMD) is connected between the switch node of each phase (phase 1 and phase 2… phase n) and the converter output voltage (VOUT) .
The secondary side is connected in series with the rest of the phases and the compensator inductor.
