The LM10502 are advanced PMUs each containing two configurable, high-efficiency buck regulators for supplying variable voltages. The device is ideal for supporting ASIC and SOC designs for Solid-State and Flash drives.

The LM10502 operate cooperatively with the application ASIC to optimize the supply voltage for low-power conditions and Power Saving modes via the SPI interface. It also supports a 250 mA LDO and a programmable Interrupt Comparator to monitor VIN.
