Texas Instruments introduced a family of tiny, single-chip, power management integrated circuits (PMICs) for powering all the supply rails in solid state drives (SSDs), hybrid drives and other Flash memory management applications. The new LM10504, LM10503 and LM10506 PMICs feature a power-saving deep sleep mode, built-in current limit and thermal protection, and power-down data protection. These new PMICs integrate three programmable 2.25-MHz DC/DC step-down converters with 95-percent peak efficiency that support core processor, memory and I/O voltages, along with a general-purpose, 3-V, 250-mA low-dropout (LDO) regulator for host controller reference. Each PMIC functions cooperatively with a controller IC to optimize the supply voltage for low power conditions and features a deep sleep mode option that lowers the core ASIC voltage and turns off the Flash and input/output rails to obtain maximum system efficiency. The LM10504 and LM10506 also include power-down data protection that ensures that the SSD controller completes the writing operation during unexpected power failure.
