BQ25703A: BQ25703A / Use 1.0uH inductor with 800kHz switching

Hi,

I know that the the recommended switching frequency for 1.0uH indcutor is 1.2MHz. Then do you have any concern if the customer use 1.0uH inductor with 800kHz switching? They understand that the peak inductor current will be increased but they want to achieve higher efficiency.
