DESCRIPTION
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.
