Frequently Asked Questions
What input voltage range does the MIC2128YML-TRVAO support and which power bus architectures does it cover?
The MIC2128YML-TRVAO accepts input voltages from 4.5 V to 75 V, covering 12 V automotive, 24 V industrial, and 48 V telecom bus architectures with a single device. This wide input range eliminates the need for separate controller ICs for different supply rails, simplifying BOM management in multi-voltage power supply designs.
How does the VQFN-16 package of the MIC2128YML-TRVAO benefit space-constrained power supply PCBs?
The MIC2128YML-TRVAO is housed in a 3x3x0.9 mm VQFN-16 package with an exposed pad for thermal dissipation, providing a significantly smaller footprint than equivalent switching controllers in SOIC-8 or DIP-8 packages. This compact size allows power supply modules operating at up to 75 V to be built into high-density boards where PCB area is limited, such as server blade power regulators or automotive ECU power stages.
What is the factory lead time for the MIC2128YML-TRVAO and what product lifetime can procurement teams expect?
The factory lead time for the MIC2128YML-TRVAO is 8 weeks, and the device has a YTEOL (years to end of life) rating of 18 years from its 2019 introduction, indicating supply availability through approximately 2037. This long product lifetime makes it a suitable choice for industrial and telecommunications equipment with 10-year or longer field service requirements.
In which types of DC-DC converter topologies can the MIC2128YML-TRVAO be used?
The MIC2128YML-TRVAO switching controller supports buck (step-down) converter topologies and is suitable for designs converting from a 75 V maximum input down to regulated lower voltages. Its 4.5 V minimum input also allows use in boost-capable architectures where the supply starts from a low 5 V or 6 V rail and must deliver higher-voltage outputs through an appropriate external FET and inductor network.
