Frequently Asked Questions
How does LTM4675EY#PBF support dual-output and single-output configurations, and what current ratings apply?
LTM4675EY#PBF operates as either dual 9A outputs or a single 18A combined output by connecting the two internal phases in parallel. In dual mode, each channel delivers up to 9A continuously from a 4.5 V to 17 V input, while parallel single mode doubles the output to 18A, making it suitable for high-current FPGA core and DDR memory rails.
What digital power management capabilities does LTM4675EY#PBF offer through its PMBus interface?
LTM4675EY#PBF supports full PMBus 1.3 digital power system management, allowing hosts to read back output voltage, output current, input voltage, and junction temperature telemetry over the 2-wire I2C/SMBus bus at up to 400 kHz. Designers can also program soft-start time, switching frequency, and fault thresholds in real time, enabling dynamic voltage margining across a ±10% range.
For a 12 V input server rail application, what output voltage range can LTM4675EY#PBF regulate to?
When powered from a nominal 12 V rail (4.5 V to 17 V operating range), LTM4675EY#PBF can regulate output voltage adjustable from approximately 0.5 V to 5.5 V via an external resistor or PMBus command. This range covers typical FPGA core voltages such as 0.9 V, 1.0 V, 1.2 V, and 1.8 V as well as DDR4 VDDQ at 1.2 V.
What package does LTM4675EY#PBF use and how does it benefit board layout compared to discrete solutions?
LTM4675EY#PBF is packaged in a 15 mm × 15 mm × 3.87 mm BGA μModule that integrates the DC-DC controller, MOSFETs, inductors, and most passives into a single surface-mount component. This integration reduces the required PCB area by more than 60% versus a discrete equivalent and simplifies routing by eliminating separate inductor footprints and gate-drive traces.
