Is there clear condition of PFM switch to PWM? I can't find the condition of PFM switch to PWM. Thanks.

Hi Ryker,

There is not 1 simple condition which determines the switch from PFM to PWM, hence it is not stated in the datasheet. In general the device will switch from PFM to PWM when load current (Isys + Ibat) is in the range of hundreds of mA.

Garrett

Hi Garrett,

Could you kindly explain the logic of PFM switch to PWM? Because our accounts are concerned about it too.

Best Regards,
