Product Summary

The TPS40180RGER is a stackable single-phase synchronous buck controller. Stacking allows amodular power supply design where multiple modules can be connected in parallel to achieve the desiredSharing (Patents Pending output power capability if the output power requirement cannot be provided by one module. Stacked modules can be configured to switch at different times while running at the same basefrequency creating a multiple phase supply. Up to eight phases can be configured, and multiple modules can be set up to switch on the same phaseif required. The applications of the TPS40180RGER include Graphic Cards, Servers, Networking Equipment, Telecommunications Equipment, Distributed DC Power Systems.
