Outputs
DESCRIPTION
LM10524 is an advanced PMU containing three
configurable, high-efficiency buck regulators for
supplying variable voltages. The device is ideal for
supporting ASIC and SOC designs for SSD and
Flash drives.
The LM10524 can operate cooperatively with an
ASIC to optimize the supply voltage for low-power
conditions and to control power saving modes via the
SPI interface.
