MPM3684GRU-Z

Product Overview

The MPM3684GRU-Z from Monolithic Power Systems Inc. is a non-isolated point-of-load DC-DC converter module for board-mounted power distribution. It accepts an input voltage range from 2.5V to 18V and provides one output from 0.65V to 5V at up to 15A. The module uses a 65-PowerBQFN surface-mount package with dimensions of 15.0mm x 12.0mm x 4.0mm, and it is specified for operation from -40°C to 85°C.

Key Features

• Single non-isolated PoL output with 0.65V to 5V output range and 15A maximum output current.
• Input voltage range of 2.5V to 18V.
• Protection features include overcurrent protection (OCP), overtemperature protection (OTP), and undervoltage lockout (UVLO).
• Surface-mount 65-PowerBQFN module measures 15.0mm x 12.0mm x 4.0mm.
• Operating temperature range is -40°C to 85°C.

Applications

• Commercial information technology equipment board power distribution.
• Point-of-load regulation close to low-voltage, high-current load rails.
• Surface-mount conversion from 2.5V to 18V input supplies to 0.65V to 5V output rails.

Design & Procurement Notes

When selecting the MPM3684GRU-Z, confirm that the system input remains within 2.5V to 18V and that the required output voltage and load current fall within 0.65V to 5V and 15A. The non-isolated single-output topology should be reviewed for grounding and layout compatibility in the intended ITE application. Layout should account for the 15A output current and the 65-PowerBQFN surface-mount module footprint, including thermal behavior over the -40°C to 85°C operating range. The OCP, OTP, and UVLO features can be considered in system protection planning, but external margin and fault-handling requirements should still be validated.
