MxL7704-B Data Sheet Five Output Universal PMIC General Description The MxL7704-B 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 3.3V power for auxiliary devices. All of the outputs support ±10% margining. The two highest power outputs also support dynamic voltage control which saves power in processors that can use this function. You can monitor an input voltage flag and PGOOD flags for each output through a 400kHz I2C interface. The I2C port can enable you to modify the power up and down sequencing options, assign PGOOD outputs to the PGOOD pins, enable outputs, and select switching frequency.
