Frequently Asked Questions
How many output channels does the MIC23451-AAAYFL T5 provide and what is the maximum current per channel?
The MIC23451-AAAYFL T5 integrates 3 independent step-down channels, each capable of supplying up to 1 A of output current with an adjustable output voltage range of 1 V to 3.3 V, enabling multi-rail power management from a single 26-pin QFN device.
Is the MIC23451-AAAYFL T5 suitable for powering FPGA core and I/O voltage rails simultaneously?
Yes. With 3 independent buck converter channels each delivering up to 1 A, the MIC23451-AAAYFL T5 can power separate FPGA core (e.g. 1 V), I/O (1.8 V), and DDR memory (1.2 V to 1.8 V) rails simultaneously, reducing BOM count and board area.
What lead time and packaging format should buyers plan for when procuring MIC23451-AAAYFL T5 in volume?
The MIC23451-AAAYFL T5 is available in tape-and-reel format (the T5 suffix indicates a 3000-unit reel) in a 26-pin QFN package. Lead times can vary; buyers planning high-volume production should verify stock and negotiate rolling forecasts with authorized distributors to avoid supply gaps.
