MXL7704-AQB-R

Overview

The MXL7704-AQB-R is a specialized five-output universal Power Management IC (PMIC) designed for low-power FPGAs, DSPs, and MCUs. It integrates four synchronous buck regulators and one LDO, operating within an input voltage range of 4 V to 5.5 V. The device supports output voltages from 600 mV to 3.6 V with ±10% adjustment margin. Key features include I2C interface control for dynamic voltage scaling, programmable power sequencing, and comprehensive fault protection including overcurrent and thermal shutdown. Packaged in a QFN-32 format, it offers high efficiency and fast transient response.

Procurement Notes

Verify component authenticity through authorized channels due to the presence of counterfeit risks in the market. Confirm that the specific suffix matches the required pinout and electrical characteristics. Check RoHS compliance status if environmental regulations apply to your deployment. Ensure proper handling procedures are followed given the moisture sensitivity classification associated with this package type.

Selection Notes

Select this PMIC when designing systems requiring integrated power sequencing and dynamic voltage regulation for ARM or Xilinx processors. Consider the QFN-32 package constraints regarding thermal dissipation and PCB layout space. Evaluate the need for I2C connectivity against simpler fixed-output alternatives. Verify that the input voltage range aligns with your system's primary power source availability.
