Hi,

Does LM2757 support pre-bias start condition?

In the customer's application, after starting, the LM2757 is turned OFF / ON and restarted.

I would like to know whether pre-bias startup support is possible.

Best Regards,

Yusuke

Hi Yusuke-san,

Thank you for posting. I will ask our designer to take a look to be sure it can support output prebias condition. I should be able to get back to you next Monday (US time).

Thanks,

Hi Yusuke-san,

Sorry it took awhile to get into the design files. In our understanding, this device should be able to support the output prebias condition.

Thanks,

Youhao
