MxL7704 Five Output Universal PMIC

MaxLinear's MxL7704 five output universal PMIC's four synchronous step-down buck regulators range from 1.5 A system power to 4 A core power

Image of MaxLinear's MxL7704 Five Output Universal PMICThe MaxLinear MxL7704 PMIC is a five output universal PMIC optimized for powering low-power FPGAs, DSPs, and microprocessors from 5 V inputs. Four synchronous step-down buck regulators range from 1.5 A system power to 4 A core power. A 100 mA LDO provides a clean 1.5 V to 3.6 V power for auxiliary devices. All outputs support ±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 400 kHz 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.
