Qorvo’s enterprise-SSD block diagram shows a 12V PMIC+PLP and a standalone 5V PMIC between the input and the SSD controller, NAND and DDR4/5 RAM, with buck converters, LDOs and OCP/OV/UV protection.
Qorvo’s ACT85411 PMIC+PLP has an input voltage range of 2.7–14.8V.
TI LM10504 is a power management unit with three configurable buck regulators; TI calls it ideal for supporting ASIC and SOC designs for solid-state and flash drives.
Qorvo’s enterprise-SSD solutions guide captions a system in which its ACT85411 PMIC+PLP and ACT88760 PMIC power a multi-rail FPGA controller and NAND interface.
Qorvo’s enterprise-SSD PMIC provides deterministic, programmable multi-rail sequencing, with a programmable power-up sequence and a power-down and reset sequence aligned to SSD-controller requirements.
