TPS40132RHBR Datasheet PDF - TI

●DESCRIPTION

●The TPS40132 is a two-phase synchronous buck controller that is optimized for low-output voltage, high-output current applications powered from a supply between 1 V and 40 V. A multi-phase converter 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.
