Frequently Asked Questions
What is the output current capability of the MIC28304-2YMP and what output voltage range can it regulate to?
The MIC28304-2YMP delivers up to 3 A continuous output current with an adjustable output voltage range of 0.9 V to 24 V. This flexibility allows it to power a wide variety of loads including FPGAs operating at 1.0 V core voltage, 3.3 V logic rails, and 12 V peripheral supplies from a single 4.5 V to 70 V input.
How does the MIC28304-2YMP 70 V maximum input rating benefit industrial 48 V bus power systems?
With a 4.5 V to 70 V input range, the MIC28304-2YMP directly accepts a 48 V industrial bus including transient spikes up to 70 V without additional input filtering. This eliminates the need for a pre-regulator stage, reducing system component count by several parts and improving overall efficiency in 48 V-powered industrial control and telecom equipment.
Which package does the MIC28304-2YMP use and how does this affect thermal dissipation on a PCB?
The MIC28304-2YMP is housed in a 64-pad exposed-pad QFN (S-XQMA-N64) package, which enables direct thermal conduction to the PCB ground plane through the exposed pad. At 3 A output with typical conversion efficiency above 90%, the thermal pad dissipates less than 1 W under most operating conditions, supporting a junction temperature range up to 125°C.
