Data Sheet MxL7704 Five Output Universal PMIC General Description Features The MxL7704 is a five output Universal PMIC optimized for
powering low power FPGAs, DSPs, and microprocessors
from 5V inputs. Four synchronous step down buck
regulators range from 1.5A system power to 4A core
power. A 100mA LDO provides a clean 1.5V to 3.6V
power for auxiliary devices. All outputs support В±10%
margining and the two highest power outputs support
dynamic voltage control to support processors that can
utilize this function to save power. Through a 400kHz I2C
interface, the customer can monitor an input voltage flag
and PGOOD flags for each output. The I2C port can also
be used to modify power up and down sequencing options,
assign PGOOD outputs to the PGOOD pins, enable
outputs and select switching frequency.
High switching frequency and a current mode architecture
with internal compensation enable a very fast transient
response to line and load changes without sacrificing
stability and keeping board space to a minimum. в– в–
