Frequently Asked Questions
What is the input voltage range of the LM5085MM/NOPB?
The LM5085MM/NOPB supports an input voltage range from 4.5V to 75V, with a nominal operating voltage of 48V. This makes it suitable for a wide range of industrial, telecom, and automotive power supply applications running off 12V, 24V, or 48V bus rails.
What control method does the LM5085MM/NOPB use?
The LM5085MM/NOPB uses voltage-mode constant on-time (COT) control. This technique provides fast load transient response, simplified loop compensation, and inherent pulse-skipping at light loads, improving efficiency across a broad load range.
What is the minimum adjustable output voltage of the LM5085MM/NOPB?
The LM5085MM/NOPB can regulate output voltage down to 1.25V in adjustable mode. The adjustable output is set using an external resistor divider, allowing designers to target any output voltage above 1.25V within the application's constraints.
What package does the LM5085MM/NOPB come in?
The LM5085MM/NOPB is available in an 8-pin MSOP (S-PDSO-G8) small outline package. This compact footprint is suitable for space-constrained designs and supports high-density PCB layouts in industrial and embedded power applications.
Is the LM5085MM/NOPB RoHS compliant?
Yes, the LM5085MM/NOPB is lead-free and RoHS compliant, as indicated by its Pbfree Code: Yes. The '/NOPB' suffix in the part number explicitly denotes no lead (Pb) in the package, conforming to global environmental and hazardous substance regulations.
