Key Features

  • Triple-channel step-down (buck) regulator with up to 1 A per output channel
  • Adjustable output voltage range from 1 V to 3.3 V per channel
  • Compact 26-pin QFN package for high-density multi-rail power designs
  • High-efficiency switching topology reduces power dissipation versus LDO solutions
  • Suitable for multi-voltage FPGA, DSP, and SoC power sequencing applications

Applications

The MIC23451-AAAYFL T5 is designed for multi-rail power supply designs in portable electronics, embedded computing modules, and communication equipment. Its three independent 1 A buck converter channels allow simultaneous regulation of core, I/O, and memory rails from a single IC. It is commonly found in FPGA evaluation boards, tablet PCs, and wireless infrastructure devices requiring efficient, compact power management.

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.
