DC/DC power supply

close

Provides DC/DC conversion from the bus voltage(s) to power all the necessary rails for operation of the SSD. This includes buck/step-down converters, LDOs, and/or a multi-rail integrated power management units (PMICs). These rails power the SSD controller SoC, the memory as well as all the other active components in the system.
