SLVU047A February 2001 – March 2022 TPS2330 , TPS2331 , TPS5102
The TPS2330/TPS2331 single-channel hot-swap controller uses external N-channel MOSFETs as high-side switches in power applications. The devices integrate features such as overcurrent protection, inrush current control, output-power status reporting, and separation of load transients from actual load increases, which are the critical requirements for hot-swap applications. For a detailed description of functions and characteristics of the TPS2300 and TPS2301 Dual Hot-Swap Power Controllers w/Independent Circuit Breaker & Power-Good Rep data sheet.
The TPS5102 is a dual-channel high-efficiency controller that drives a synchronous-rectifier buck converter. With PWM and skip operating modes, dead-time control, and very low quiescent current, the controller allows power to be conserved under all load conditions. For a detailed description of functions and characteristics of the TPS5102 Dual High Efficiency Controller For Notebook PC Power data sheet.
Refer to the data sheets to select appropriate peripheral components for the controllers. For different applications, a gate capacitor at the TPS2330/TPS2331 GATE output can be required to limit excessive inrush current or very heavy load. Recommended input capacitors can help hold the input voltage in the designed range.
To learn more about InfiniBand power-management requirements, users can go to www.infinibandta.org for a copy of the InfiniBand specification 1.0, and can also read the application report Power-Management Solutions for InfiniBand I/O Modules from Texas Instruments on https://www.ti.com/support-packaging/find-packages.html.
To assist designers in the evaluation of the hot-swap controllers, a set of evaluation modules has been developed: one is the InfiniBand bulk power EVM, and the other is an interface card.
