MPS MP5515 User Manual

DESCRIPTION
The MP5515 is an input power conditioning
PMIC targeting enterprise solid-state drives,
NVDIMM, and other applications with back-up
system requirements. The MP5515 consists of
input current limiting, input reverse current
blocking, and an MPS-patented, high-efficiency,
bidirectional, boost-buck converter with only
one inductor for energy storage and system
back-up power when there is an input power
failure. The MP5515 also provides I
and ADC. By using the I
input current limit, slew rate, and perform cap
health tests. The MP5515 can also monitor
system status, such as input voltage, input
current, storage voltage, temperature, and
provide interrupt options for these features.
The internal input current-limit block prevents
inrush current during system start-up while the
reverse-current block prevents backup energy
from flowing to the failing VIN port. MPS's
patented energy
management control circuit minimizes the
storage capacitor requirement. It pumps the
input voltage to a higher backup voltage and
releases the energy over a hold-up time to the
system bus voltage in case of an input outage.
The MP5515 requires a minimal number of
standard, external components and is available
in a 30-pin QFN (5mmx5mm) package.
