Frequently Asked Questions

What is the input voltage range of the LM25085QMY?

The LM25085QMY supports an input voltage range of 4.5V to 42V, making it suitable for automotive systems with nominal 12V or 24V rails, as well as industrial power supplies with wide input fluctuations.

What control method does the LM25085QMY use?

The LM25085QMY uses a constant on-time (COT) voltage-mode control technique. This approach provides fast transient response, inherent discontinuous conduction mode (DCM) operation at light loads, and eliminates the need for loop compensation in many designs.

What are the typical applications for the LM25085QMY?

The LM25085QMY is designed for automotive and industrial DC/DC step-down (buck) converter applications. Typical uses include point-of-load regulators in automotive infotainment systems, ADAS modules, industrial control boards, and any system requiring a robust PFET-based buck controller with wide input voltage support.
