Key Features
- Triple independent buck converter channels each rated at 2 A continuous output current
- Adjustable output voltage from 1 V to 3.3 V per channel covers common FPGA, DSP, and I/O rails
- High-frequency switching minimizes external inductor and capacitor size for dense PCB designs
- 32-pin MLF (QFN) package with exposed thermal pad reduces board area vs. discrete multi-regulator solutions
- Integrated power-good signals and enable pins for sequenced power-up of multi-rail digital loads
Applications
MIC23450-AAAYML T5 is used in multi-rail power supply designs for FPGAs, DSPs, and application processors where core voltage, I/O voltage, and memory supply must each be independently regulated at up to 2 A from a common input rail. Its triple-channel integration in a single 32-pin MLF package makes it popular in wireless access points, embedded computing modules, and industrial SoC boards where minimizing regulator component count and PCB area is a design priority.

Frequently Asked Questions
How much output current can each channel of MIC23450-AAAYML T5 supply simultaneously?
Each of the three independent buck converter channels in MIC23450-AAAYML T5 is rated at 2 A continuous output current, and all three channels can operate simultaneously. This gives a total of up to 6 A across the three rails, which is sufficient to supply core, I/O, and DDR memory voltages for a mid-range FPGA or application processor simultaneously.
What output voltage range does MIC23450-AAAYML T5 support, and which processor supply rails does that cover?
MIC23450-AAAYML T5 adjusts each channel from 1 V to 3.3 V, covering FPGA core voltages around 1.0 V to 1.2 V, DDR memory interface rails at 1.35 V to 1.8 V, and standard 3.3 V I/O supplies. This range makes it directly usable on boards with Xilinx Zynq, Intel Cyclone, or Microchip SAMA5 processors without external pre-regulation.
How does the 32-pin MLF package benefit thermal management in a high-current multi-rail design?
The 32-pin MLF (QFN) package includes an exposed thermal pad soldered to a ground copper pour on the PCB, which conducts heat from all three 2 A switching channels directly into the board. At maximum load across all channels, the low package thermal resistance helps keep junction temperature within safe limits on a standard 4-layer PCB with adequate copper area.
Can MIC23450-AAAYML T5 be used to sequence power rails for an FPGA startup, and does it have enable controls?
Yes. MIC23450-AAAYML T5 provides individual enable pins for each of its 3 channels, and power-good output signals indicate when each rail has reached regulation. These features allow a simple RC-timed or GPIO-driven power sequencing scheme to bring up FPGA core, I/O, and auxiliary 3.3 V rails in the correct order during startup without a dedicated sequencer IC.
