TPS40090 Datasheet (Texas Instruments)

TPS40090, MULTIPHASE CONTROLLER

The TPS4009x is a two-, three-, or four-phase programmable synchronous buck controller that is optimized for low-voltage, high-current applications powered by a 5-V to 15-V distributed supply.

A multi-phase converter offers several advantages over a single power stage including lower current ripple
