Dear all,

Could you teach me about how to calculate VIN_OVP?

I cannnot understand how to calculate 'VSET_DCDC+6..10'.

Best regards,

    Hi Yamamoto-san,

    Vset_dcdc is automatically adapted boost out voltage by LED forward voltage. When Vin is too high, Vboost can be lower than Vin, but still higher than required(Vset_dcdc) boost out voltage by 6~10V(this variation is because of feedback detection tolerance). In this case, Vin OVP will be triggered.

    Hope this helps,
