MXL7704-BQB-R

Overview

The MXL7704-BQB-R is a specialized Power Management IC (PMIC) manufactured by MaxLinear, designed for low-power FPGA, DSP, and MCU applications. It integrates five output channels: four synchronous buck regulators and one low-dropout regulator (LDO). The device features an I2C interface for dynamic voltage regulation, power sequencing control, and PGOOD status monitoring. It operates within an input voltage range of 4 V to 5.5 V and supports output voltages from 600 mV to 3.6 V. The component is housed in a QFN-32 package and functions across a temperature range of -40°C to +125°C.

Feature Summary

• Integrates four synchronous buck regulators and one LDO for comprehensive multi-rail power management.
• Provides programmable power-up/down sequencing via I2C interface to prevent latch-up and ensure system stability.
• Includes PGOOD status monitoring outputs for real-time health supervision of all regulated rails.

Applications

• Power management for low-power FPGAs
• Power sequencing for DSP systems
• Multi-rail supply for MCU-based edge devices

Procurement Notes

Verify the specific suffix BQB against official MaxLinear documentation to confirm pinout and electrical characteristics, as suffixes often denote package or tape/reel variations. Confirm current availability status, as this part number may be subject to discontinuation notices. Ensure compatibility with existing PCB footprints and I2C address configurations before procurement.

Selection Notes

Select the MXL7704-BQB-R when designing systems requiring integrated sequencing for multiple voltage rails in space-constrained environments. It is suitable for applications needing precise control over power-on order to protect sensitive logic components. Consider thermal dissipation requirements given the QFN-32 package and potential power dissipation levels under load conditions.
