Frequently Asked Questions
What is the input voltage range supported by the LM25085SD?
The LM25085SD supports an input voltage range of 4.5 V to 75 V, making it suitable for a wide variety of industrial, automotive, and telecom power supply applications where input voltages can vary significantly.
How much output current can the LM25085SD deliver in a buck converter design?
The LM25085SD can deliver up to 2 A of continuous output current when properly configured with external power components, making it appropriate for medium-power point-of-load and distributed power system designs.
What control topology does LM25085SD use and why does it benefit transient response?
LM25085SD uses a constant on-time (COT) control topology with a minimum on-time of 200 ns. This approach allows the regulator to react quickly to load transients without a traditional error amplifier compensation network, simplifying design and improving dynamic performance at high step-down ratios.
In which package is LM25085SD available and what are its dimensions?
LM25085SD is available in an 8-pin SOIC (SO-8) surface-mount package, which measures approximately 4.9 mm x 3.9 mm. This compact footprint allows integration into high-density PCB layouts with minimal board area consumption.
