SN6505B: required voltage for the gate drivers is in the range of +15..16V and -7..-8V

Part Number: SN6505B

Dear team,

My customer want to use SN6505BDBVR for high side IGBT transistors gate drive supply – replace existing boot-strap supplies

The required voltage for the gate drivers is in the range of +15..16V and -7..-8V

Can you please advise for the following questions:

1) Is it possible to drive three push-pull transformers (1W each) from one  SN6505BDBVR?

2) They are looking for 1W push-pull transformer for SN6505BDBVR to get +15..16V and -7..-8V outputs, Is there any recommendation from TI? 

Please advise the above, thanks in advance.

Sincerely, 

Shai Berman

  • Hi Shai,

    Please find below my response to your questions,

    1) Yes, it should be fine drive three push-pull transformers from one SN6505B.

    2) I am not aware of any multi-output transformers that could provide provide both +15V & -8V. You can find some multi-output transformers at the link below that can be used with SN6505B, please check which one of them suits you the best. You can also get a customer transformer made to meet your requirements.
