Description

The TPS40130 is a two-phase synchronous buck controller that is optimized for low-output voltage, high-output current applications powered from a supply between 3 V and 40 V. A multi-phase con- verter offers several advantages over a single power stage including lower current ripple on the input and output capacitors, faster transient response to load steps, improved power handling capabilities, and higher system efficiency. Each phase can be operated at a switching frequency up to 1 MHz, resulting in an effective ripple frequency of up to 2 MHz at the input and the output. The two phases operates 180 degrees out-of-phase.
