MXL7704-AQB-R

MXL7704-AQB-R is a five output universal PMIC. It is 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. 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 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. Application includes low power processor, ASIC and FPGA power, industrial control, test equipment, POS terminals.
