High-density power module fits compact AI servers

Enabling higher power delivery within the same rack space, Microchip’s MCPF1525 power module delivers up to 25 A per device and can be stacked to 200 A. The module integrates a 16-V_IN buck converter with programmable PMBus and I²C control, making it well suited for powering PCIe switches and high-compute MPU applications used in AI deployments.

With dimensions of approximately 6.8×7.65×3.82 mm, the MCPF1525’s vertical construction maximizes board space, providing up to a 40% reduction in board area compared to alternative solutions. For improved reliability, the device incorporates multiple diagnostic functions reported over PMBus, including overtemperature, overcurrent, and overvoltage protection to help prevent undetected faults.

Housed in a thermally enhanced package, the MCPF1525 supports a junction temperature range from −40°C to +125°C. An embedded EEPROM enables users to program the default power-up configuration.

The MCPF1525 is available now, priced at $12 each in 1000-unit quantities.
