ADP5070 transient response from PFM mode to PWM

Our customer has issue with transient response.

The requirement is as below,


Vout1=15V 100mA

Vout2=-9V 100mA

Iout is pulsating flow 10mA to 100mA at 160Hz.


I don't think ADP5070 can disable the PFM because of non-synchronous DC/DC converter.

But do you have idea to improve transient response?

They found 2V transient when the flow is changed 10mA to 100mA.


Now the customer uses ADP5070EVB to tune it up in their system.
