LP87745-Q1: How to change the SW frequency of BUCK from 17.6MHz to 8.8MHz?

Part Number: LP87745-Q1

Hello Expert, 

Could you help to check how to change 0x78 register's value?  My customer tried to change this register to make SW frequency of BUCK from 17.6MHz to 8.8MHz, but failed. 

Can this register be written or it can only be read?

In the picture 1, these registers circled can not be found in datasheet. Are there some guidance on how to modify them?

In the picture 2, the maxim value of the register can only be achieved 0x46?

Best regards,

Wenting

    Hello Wenting,

    Switching frequency cannot be changed by user. It is only configurable while OTP definition. If they want sample with another switching frequency they need to ask for new samples or order another OPN with that switching frequency.
