Hi.
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 ?
Thanks
Mario
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.
