Datacenters and server farms contain vast amounts of digital electronics, such as ASICs, FPGAs, and CPUs. Powering, monitoring, and managing power consumption at every node -- down to the board level -- is a challenging task facing designers of today’s systems. Fault management, flexible power sequencing, making changes-on-the-fly, and debugging of these systems requires a new approach to board-mount power: integrating DC/DC conversion with Digital Power System Management (DPSM).
The LTM®4676 is a dual 13A or single 26A output step-down DC/DC µModule (micromodule) regulator with an I˛C-based interface, making it suitable to power today’s digital electronics and communicate with board-mount controllers (BMCs) and embedded systems and meld with Intelligent Platform Management Interface (IPMI) functions. With ±1% DC output error over temperature, ±2.5% current readback accuracy, an integrated 16-bit delta-sigma ADC and EEPROM, the LTM4676 combines best-in-class analog switching regulator performance with precision mixed signal data conversion.
The LTM4676 tackles the challenges of DPSM and provides a compelling “digitally-enhanced” DC/DC solution in a small, 16mm x 16mm x 5mm BGA package.
