ADP5090 Minimum Input Voltage for Cold Start

Hi All,


My customer is considering step-up regulator such as ADP5090 for his new design.

He desires low start up voltage as low as possible.

ADP5090 minimum input voltage for cold start is 380mV, however he is expecting several mV of the input voltage for cold-start such as 50mV.

Do you have any idea to lower the input voltage?

Some externally connected device will be acceptable.


Best Regards,
