Frequently Asked Questions
What is the input voltage range of the LM25085ASD?
The LM25085ASD supports an input voltage range of 4.5V to 42V, making it suitable for a wide variety of power supply designs including automotive, industrial, and general-purpose 12V and 24V systems.
How is the output voltage set on the LM25085ASD?
The output voltage of the LM25085ASD is adjustable and set using an external resistor divider connected to the feedback pin. This allows designers to configure any output voltage down to 0.9V, offering great flexibility for different load requirements.
What control topology does the LM25085ASD use?
The LM25085ASD uses a constant on-time (COT) voltage-mode control technique. This hysteretic architecture provides fast transient response, simplifies loop compensation, and enables stable operation with a wide range of output capacitors including low-ESR ceramic types.
What is the peak switch current of the LM25085ASD?
The LM25085ASD has a peak switch current of 580mA. This limits the maximum deliverable output current, so designers should verify the load current requirements against the duty cycle and inductor ripple when selecting this device.
Is the LM25085ASD RoHS compliant?
Based on the available data, the LM25085ASD is listed as non-RoHS (Pbfree Code: No), meaning it may contain lead. Designers targeting RoHS-compliant end products should verify with Texas Instruments or select the appropriate lead-free variant if one is available.
