LP5569: charge pump specification

user6519235

Part Number: LP5569

Hello,
I have a question about charge pump specification.

condition : cp_mode=11 ,cp_return_1x=1 ,powersave_en=1

If the VIN voltage drops once and the 1.5 x mode is turned on,

and then the VIN voltage rises due to battery charging,

is it a specification to keep the 1.5 x mode while the LED is lightening?

    Hello,

    When setting the registers as the following:

    cp_mode=11 ,cp_return_1x=1 ,powersave_en=1

    If the VIN voltage drops once and the 1.5x mode is turned on and then the VIN voltage rises due to battery charging, charge pump will return to 1x mode while the LED is lighting.

    Best Regards
