I'm controlling the outputs through the SPI interface and I'm using just 4 of the high power outputs (LED outputs are also unused). I' m trying to figure out what power DC/DC convertor I need to use to isolate the supply in a project.</P><P></P><P>Best regards,</P><P></P><P>Ondrej</P></BODY></HTML> Tue, 11 Dec 2018 10:39:26 GMT https://community.nxp.com/t5/Power-Management/Power-dissipation-on-MC33882/m-p/786421#M57 ondrej_brejla 2018-12-11T10:39:26Z Re: Power dissipation on MC33882 https://community.nxp.com/t5/Power-Management/Power-dissipation-on-MC33882/m-p/786422#M58 <HTML><HEAD></HEAD><BODY><P>Hi Ondrej,</P><P>&nbsp;</P><P>According to the device specification on page 3, VPWR Supply current is max 7.5mA, so make sure you select your DC/DC converter according to this specification.<BR /> <BR /> Unfortunately, there is no further detailed information about the consumption of the MC33882. &nbsp;</P><P><BR />Have a great day,<BR />Jose</P><P></P><P>-----------------------------------------------------------------------------------------------------------------------<BR />Note: If this post answers your question, please click the Correct Answer button.
