TPS40132RHBT

illustrate

The TPS40132 is a two-phase synchronous step-down controller for applications with high output current powered by a multi-phase converter from 1 to V and 40 V and provides several advantages over a single power stage, including low ripple current at input and output capacitors, faster transient response to load steps, improved power handling capability and higher system efficiency.

Each stage can be maintained at switching frequencies up to 1MHz, generating an effective input and output ripple frequency of up to 2 MHz. The two stages of work are 180 degrees out of phase.
