Frequently Asked Questions
What are the input and output voltage ranges of the LTM4678IY?
The LTM4678IY accepts input voltages from 4.5 V to 16 V and produces output voltages adjustable from 0.5 V to 3.4 V. In dual-channel mode, each channel delivers up to 25 A; in single parallel mode, combined output reaches 50 A. This flexibility suits a wide range of digital core and I/O voltage rails in modern FPGA and ASIC designs.
How does the PMBus interface on the LTM4678IY enable power system management?
The LTM4678IY's PMBus interface allows real-time monitoring of output voltage, output current, input voltage, and junction temperature through standard 2-wire digital communication at 100 kHz or 400 kHz. Designers can program output voltage, current limits, fault thresholds, and switching frequency via PMBus commands, enabling centralized power management and predictive fault detection across multi-rail server and telecom platforms.
What is the LTM4678IY package type and how does it affect board layout?
The LTM4678IY is housed in a BGA (Ball Grid Array) package with an integrated inductor, power switches, and passives in a complete µModule design. This integration eliminates the need for 20 to 30 external components, reducing PCB area by over 50% compared to discrete regulator designs. The BGA footprint enables dense power rail placement close to FPGA and processor load points to minimize parasitic inductance.
Can LTM4678IY channels be paralleled for loads exceeding 25 A per rail?
Yes, the LTM4678IY internally parallels its two 25 A channels to deliver a single 50 A output using active current sharing that balances current within 2 A between phases. Multiple LTM4678IY modules can also be cascaded externally for even higher current, with clock synchronization via the CLKIN/CLKOUT pins to reduce output ripple and simplify filter design for demanding processor and FPGA core power applications.
