Isolated DC-DC converter for Lithium Ion battery operated application

Hi There,

I need to use a Isolated DC to DC converter which will have an input of 3.7V Lithium Ion battery and output should be 3.3V. I was looking at LTM8046, But the input voltage range does not match. Can you please suggest a part for same application and output current of 1A.

  • Hi there,

    Hey Ron.p, Thanks for the suggestion but the IC LTM8067 cannot support required currents (500mA) at 3V input Voltage.

    So I have searched and selected IC LTM8045. It can support the current, but Isolation is not available. 

    I have designed a schematic out of it. can you please review and let me know if it is OK for output voltage 3V3?
