WEBENCH® Tools/LM5002: LM5002

Part Number: LM5002
Other Parts Discussed in Thread: PMP20183, TPS55340

Tool/software: WEBENCH® Design Tools


I have already written about it...

I would like to have a boost power supply with input 3.7 lithium battery  (minimimum 3.2V maximum 4.2V) and output 75V  75mA.

is it any component ok for this ?

Can i do it with webench ?



  • Hello Mario,

    We do not have an IC that supports this input and output voltage range directly. I think the best solution is to use a converter to generate a lower voltage and then increase the voltage with charge pumps, similar to PMP20183.

    Please give me some time to check for the best converter.

  • Hi Mario,

    I would suggest the converter TPS55340 with a flyback typology. you can find some TPS55340 flyback circuit from the device folder. but the transformer need to redesign.
