Frequently Asked Questions

What is the maximum input voltage the LM25085MME can handle in a buck converter design?

The LM25085MME supports an input voltage range from 4.5 V to 42 V, making it suitable for industrial 24 V bus applications and automotive environments where supply rails may fluctuate well above the nominal 24 V operating point.

How does the constant on-time control technique in LM25085MME benefit power supply designs?

Constant on-time control eliminates the need for complex error-amplifier compensation, enabling simpler designs. The LM25085MME achieves fast transient response with a single control function, reducing design time and external component count in 42 V step-down applications.

What output voltage range can be set with the LM25085MME?

The LM25085MME supports an adjustable output voltage starting from 1.25 V, set via external resistor dividers. This flexibility allows designers to target common rails such as 1.8 V, 3.3 V, or 5 V from a wide 4.5 V to 42 V input in a compact 8-pin SOIC footprint.
