High Efficiency Step Down Converter for Storage SSD ASIC Core Rail Reference Design
Texas Instruments
Description
The PMP7340 uses the TPS53319 synchronous-buck SWIFT converter with integrated power MOSFETs using PowerStack technology to provide a highly efficienct: power dense 12V input to 1V output 5.7A solution . The TPS53319 is ideal for powering low-voltage: high-current SSD Controller ASICs as well as DDR core memory rail.
