Frequently Asked Questions
What input voltage range does the MIC28516T-E/PHA support, and how does this benefit high-voltage industrial designs?
The MIC28516T-E/PHA accepts input voltages from 4.5V to 70V, covering a wide range that suits industrial bus voltages of 24V, 48V, and even 60V systems. This breadth eliminates the need for pre-regulators in many high-voltage rail applications.
How much output current can the MIC28516T-E/PHA deliver, and is it sufficient for powering multiple loads simultaneously?
The MIC28516T-E/PHA delivers up to 8A continuous output current, which is sufficient for powering multiple low-power microcontrollers, FPGAs, or analog subsystems simultaneously from a single regulator. Its synchronous design minimizes conduction losses at this current level.
Which package does MIC28516T-E/PHA use, and what are the thermal and layout considerations for a 70V/8A converter?
The device comes in a 32-pin VQFN package (Manufacturer code VQFN-32), which provides an exposed pad for enhanced thermal dissipation. Proper PCB layout with a solid ground plane and low-impedance input capacitors is essential when switching at high voltages and 8A load.
