MPM54304GMN-0065

Voltage Regulators - DC DC Switching Regulators Overview

The MPM54304GMN-0065 is a quad-output DC/DC step-down power module from Monolithic Power Systems. It integrates four high-efficiency buck converters, inductors, and logic interfaces within a compact LGA package. The device supports an input voltage range of 4V to 16V. Channels 1 and 2 deliver up to 3A continuous current, while channels 3 and 4 provide up to 2A. Output voltages are adjustable via I2C or resistor dividers, ranging from 0.55V to 5.4V. The module features a default switching frequency of 1.6MHz, configurable GPIOs, and comprehensive protection mechanisms including UVLO, OCP, and thermal shutdown.

Voltage Regulators - DC DC Switching Regulators Procurement Notes

Verify the specific suffix code against official MPS documentation to confirm factory-programmed parameters such as output voltage and sequencing. Confirm that the required I2C address and control logic align with the target system design before procurement. Ensure ESD handling protocols are followed due to moisture sensitivity classification.

Voltage Regulators - DC DC Switching Regulators Selection Notes

Select this module when space constraints require integrated inductors and multiple regulated outputs. Consider the 1.6MHz switching frequency for reduced passive component size. Evaluate the need for digital programmability versus fixed resistor divider configurations. Verify that the total load requirements across all four channels fit within the specified current limits.
