To confirm using INN3 series to design 25V output voltage

Posted by: IalJnI on

Dear expert,

     can I use INN3 series product to design 25V output voltage CC profile? because I note that the absolute voltage of Vo pin is 27V。If it is so that , it exist what is dangerous。Thanks!

Hello IalJnI,

Thank you for you interest in our product.

Yes, you may use InnoSwitch™3 series products to design 25V output voltage CC profile. 

Make sure regulation is tight enough that your output voltage does not exceed 27 V. You may use DER-815 - 45 W 24 V Output Isolated Flyback Power Supply for Smart Speakers and Tubular Motors Using InnoSwitch3-CP as your reference in designing your device. The regulation of the device is tight enough to not exceed regulation.

Please ensure to use the corect sense resistor. The external current sense resistor connected between ISENSE and SECONDARY GROUND pins is used to regulate the output current in constant current regulation mode.Please refer to the design guide.

We hope this helps you with your concern.



Best Regards,
