Product Overview
Description
The MPM54304 integrates four 3A buck converters with built-in inductors, control circuits, and power MOSFETs in a single compact package. This high-density power module simplifies power supply design by eliminating inductor selection and reducing external component count.
Each channel operates independently with programmable output voltages from 0.6V to 3.3V, supporting various load requirements in FPGA, ASIC, and processor applications. The integrated solution delivers up to 94% peak efficiency while occupying minimal PCB area.
Advanced features include I2C interface for monitoring and control, programmable soft-start, power good indicators, and comprehensive protection functions. The module operates over a wide 4V to 16V input range, making it suitable for 5V and 12V bus applications.

FAE Expert Insights
"The MPM54304 is my go-to recommendation for multi-rail FPGA power designs. The integration level is exceptional - four complete buck converters with inductors in a 7x7mm package is remarkable. I've used this in several Xilinx and Intel FPGA designs with excellent results. The I2C interface is particularly useful for sequencing and monitoring. The efficiency is consistently 2-3% better than discrete solutions. My only caution is thermal management - with four channels at full load, you need adequate copper area and possibly airflow. I recommend at least 4-layer boards with solid ground planes for best performance."

Frequently Asked Questions
What is the recommended PCB layout for the MPM54304?
For optimal performance: 1) Use a 4-layer board with solid ground and power planes. 2) Place input capacitors close to VIN pins. 3) Provide adequate copper area (minimum 2 sq inches) for thermal dissipation. 4) Keep sensitive analog traces away from switching nodes. 5) Use multiple vias for ground connections. 6) Follow the layout guidelines in the datasheet for best EMI performance.
Download the MPM54304 layout guide or contact our FAE team for layout review services.
How do I program the output voltages via I2C?
The MPM54304 I2C interface allows voltage programming from 0.6V to 3.3V in 10mV steps. Use the MPS Virtual Bench GUI or direct I2C commands. The device address is configurable via external resistors. Write to registers 0x01-0x04 to set each channel's output voltage. Read registers 0x10-0x13 to monitor output voltages and temperatures. The I2C interface also enables channel enable/disable and fault monitoring.
Download the MPS Virtual Bench software and MPM54304 programming guide for detailed instructions.
What is the thermal performance at full load?
At full load (4 channels x 3A = 12A total), with 5V input and 3.3V output, the MPM54304 dissipates approximately 4-5W. Junction temperature rise is about 40-50°C above ambient with standard PCB layout (2 oz copper, 4 layers). For reliable operation below 125°C junction, keep ambient below 75°C or provide airflow. Thermal vias under the package help transfer heat to inner layers. The I2C interface provides real-time temperature monitoring for thermal management.
Use MPS's thermal calculator to simulate your specific operating conditions and board configuration.
Can the channels be paralleled for higher current?
The MPM54304 channels are designed for independent operation and cannot be directly paralleled. For higher current requirements, consider the MPM3695-10 (10A single output) or use multiple MPM54304 devices with current sharing controllers. Alternatively, the MPQ8636 (6A) or MPQ8862 (12A) offer higher single-channel current capability with similar integration benefits.
Contact our FAE team for high-current power architecture recommendations using MPS products.
What protection features are integrated?
The MPM54304 includes comprehensive protection: 1) Over-current protection (OCP) - cycle-by-cycle current limiting. 2) Over-voltage protection (OVP) - latches off if output exceeds 120% of set point. 3) Under-voltage lockout (UVLO) - disables operation below 3.5V input. 4) Over-temperature protection (OTP) - shuts down at 150°C junction. 5) Short-circuit protection - hiccup mode for sustained shorts. Fault status is readable via I2C interface.
Review the protection specifications in the datasheet for your application's safety requirements.
