LM3406HV use with solenoid instead of LED

Hi Clinton,

Thank you for the fast response. Also, do you know if we have a part similar to the LM3406 with a built in oscillator?

Thank you,
Jared

I'm not sure how much current you need or the input voltage required but the TPS92513 is a 1.5A buck with a fixed adjustable switching frequency. If 1A is enough (and the input voltage is low enough) the LM3405A is a fixed 1.6MHz buck. Both are current mode control so they don't have as fast of a response to transients a hysteretic type converter like the LM3406 will but that may not be an issue.

Hi Clinton,

I apologize, but do you have any parts that have the built in oscillator that are automotive grade?

Thank you,
Jared

We do but they are multi topology parts so they are more complex. But the LM3424 and the TPS92691 are both capable of buck operation and are fixed frequency and Q grade.
