MXL7704-XQB-R

Overview

The MXL7704-XQB-R is a specialized five-output universal PMIC from MaxLinear, housed in a QFN-32 package. It operates within an input voltage range of 4 V to 5.5 V and delivers up to 4 A output current. The device features four synchronous buck regulators and one LDO, with adjustable output voltages ranging from 600 mV to 3.6 V. Designed for low-power FPGAs, DSPs, and microprocessors, it supports I2C control, dynamic voltage scaling, and includes comprehensive fault protection mechanisms such as overcurrent and thermal shutdown.

Feature Summary

• Integrates four synchronous buck converters and one LDO for multi-rail power delivery
• Supports dynamic voltage scaling and ±10% voltage margin adjustment via I2C interface
• Includes built-in fault protection against input undervoltage, overcurrent, and thermal events

Applications

• Powering Xilinx Zynq Ultrascale+ MPSoC series devices
• Supplying ARM Cortex-A series processors including A7, A9, and A53 cores
• Low-power FPGA and DSP system power management

Procurement Notes

Verify component authenticity through authorized channels due to end-of-life status. Confirm RoHS compliance details and moisture sensitivity levels before storage. Ensure proper handling procedures are followed given the QFN-32 surface mount packaging requirements.

Selection Notes

Select this PMIC when designing systems requiring integrated multi-output power solutions for ARM or Xilinx processors. Consider its I2C configurability and dynamic voltage scaling capabilities for optimizing power efficiency in portable or embedded applications.
