Rack & server power

Address the power density and efficiency needs of the future with products and system-level products for rack and server applications

Changes in server and telcommunication power supplies include, increased functionality and power-level requirements. Complying with standards such as Modular Hardware System-Common Redundant Power Supply (M-CRPS) and 80 Plus Titanium efficiency are necessitating the use of gallium nitride and more complex real-time control, while higher switching frequencies and faster transient response specfications require system-level changes. Our C2000™ microcontrollers and reference designs address the ever-changing landscape of telecommunications and server power.

Why choose TI for telecom & server power applications?


Maximize efficiency

Our gallium-nitride devices enable higher-efficiency topologies that can help meet standards such as 80 Plus Titanium and Modular Hardware System-Common Redundant Power Supply (M-CRPS).


Increase power density

Our novel approach to circuit integration enables faster switching speeds to help reduce system size, while our high-performance packages facilitate greater power dissipation in a smaller area.


Create secure systems

Our C2000™ microcontrollers have security features that protect systems, while including the latest firmware to make them easy to update.

Engineering efficiency for rack and server power designs

High-performance smart switches

Gallium-nitride (GaN) transistors are wide band-gap devices capable of switching at higher frequencies than traditional silicon field-effect transistors. GaN devices also have lower capacitance and zero reverse recovery, which enables their use in topologies that were previously not achievable with silicon.

Integrated smart gate drivers help reduce parasitics and ensure the presentation of the correct drive signal to the gate of the device. In addition, gate drivers help enable protection and monitoring features such as overcurrent, overtemperature, zero current and voltage detection.

Our GaN devices enable server power-supply units to achieve 80 Plus Titanium efficiencies in smaller sizes than previous systems.
