Looking for Boost Solution

Other Parts Discussed in Thread: TPS40210, LM3478, LM5155, LM5001

Hello

if you have below proper solution : Vin =12V , Vout(max)=60-75V ,Iout is small, less then 100mA;  by the way, Vout should be independently ajustable, system will need several dozens of Vout voltage point; and regulate way could be any way like PWM/ I2C/Button, even use Digital Power if needed

    Hi Fandy,

    I would recommend the LM5001 if your Vout is not more than 70V. The LM5001 is a boost converter, integrated with a 76v MOSFET. If you use it for 75V output, there would not be much margin, because the 76V is the abs max rating on the FET. In this case, you may consider to use our controller and an external MOSFETs. We have a new device LM5155, sampling now and RTM soon, and also have other parts to support your applications: TPS40210, LM3478/81, LM502, etc, to consider. Please check the these out at TI.com.

    Best Regards,
    Youhao

    Hi Youhao
    I 'd like to use LM5001，If you have the way to dymatic regulate Vout of LM5001 solution, PWM is the best.
