TPS40180 描述

The TPS40180 is a stackable single-phase synchronous buck controller. Stacking allows a modular power supply design where multiple modules can be connected in parallel to achieve the desired 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 base frequency creating a multiple phase supply. Up to eight phases can be configured, and multiple modules can be set up to switch on the same phase if required. Input and output ripple current reduction occurs as well when modules are stacked. Stacked modules can be used to generate separate output rails, load share into a single rail or a combination of the two while sharing phase information to reduce ripple currents at the input of the system.
