MXL7704-XQB-R

MXL7704-XQB-R is a MxL7704 five output universal PMIC optimized for powering low power FPGAs, DSPs, and microprocessors from 5V inputs. 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, and POS terminals.
