Frequently Asked Questions
What is the maximum output current per channel that LTM4668AEY#PBF can deliver?
Each of the four output channels in the LTM4668AEY#PBF supports a continuous output current of up to 1.2 A, giving a combined peak capability of 4.8 A across all channels when operating from a 2.7 V to 17 V supply rail.
Which input voltage buses are compatible with the LTM4668AEY#PBF in a standard server or telecom shelf design?
The LTM4668AEY#PBF operates from 2.7 V to 17 V input, making it compatible with the 5 V, 12 V, and intermediate-bus voltages commonly found in server backplanes and telecom shelf architectures, while its PWM current-mode topology maintains regulation across load steps up to 1.2 A per output.
How does the BGA package of LTM4668AEY#PBF affect PCB layout for a 4-layer board?
The BGA package (Analog Devices manufacturer code 05-08-1600) requires via-in-pad or dog-bone fan-out routing on a 4-layer PCB, but its small footprint concentrates all four switching regulators in one compact area, reducing the total board space needed compared to four discrete converters handling 1.2 A each.
When was the LTM4668AEY#PBF introduced and what is its expected longevity for long-lifecycle industrial designs?
The LTM4668AEY#PBF was introduced on 2019-08-21, with a YTEOL rating of 9 years, making it a viable choice for industrial and embedded control designs requiring a multi-rail regulator with a stable supply and 1.8 V to 5.5 V output voltage coverage.
