I am designing a product that will step down 12V to 5V in an automotive application. I am currently considering an MP1584 step down converter into an MIC29150 linear regulator. The MP1584 has a drop out of >2V which doesn't give me as much allowance as I would like for crank scenarios when the battery voltage drops. My preference is SOIC or DIP packages at present. Temp range -10 to 85 degC is fine.
- Does TI have a replacement to the MP1584 that is high frequency, low drop out (<1V)?
- Does TI have a product that incorporates both the step-down regulator and linear regulator in one chip?
Thanks in advance.
