I found a good IC, PT2000, but it cannot be used due to the conditions of Vboost &lt;=72. I have to meet Vboost conditions above 120V.<BR />Did you find any suitable solution?<BR />If possible, could you share it with me?</P><P>Best Regards</P><P>Jooin Lee</P> Wed, 02 Dec 2020 17:57:36 GMT https://community.nxp.com/t5/Power-Management/Piezo-fuel-DI-injector-Driver/m-p/1192511#M1276 Jooin 2020-12-02T17:57:36Z
