Description

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.

The TPS40180 is optimized for low-output voltage (from 0.7-V to 5.8-V), high-output current applications powered from a 2-V to 40-V supply. The TPS40180 converts from 15-V input to 0.7-V output at 1 MHz. Each phase can be operated at a switching frequency up to 1 MHz, resulting in an effective ripple frequency of up to 8 MHz at the input and the output.

With eTrim™, the TPS40180 gives the user the capability to trim the reference voltage on the device to compensate for external component tolerances, tightening the overall system accuracy and allowing tighter specifications for output voltage of the converter.
