Hi,
When designing without a ripple injection circuit, what merit or disadvantage can be considered?
If it is required, why is it necessary?
My customers are confirming normal operation by removing the ripple injection circuit against the phenomenon that the load response can not follow and the UVP or OVP of the FB pin is applied and the device stops. Therefore, I would like to present the merits, demerits and reasons (if necessary) to the customer, which can be thought out by removing the ripple injection circuit at TPS53319.
<condition>
Vin=19V,Vout=5V,Iout=10A,injection voltage level=30~40mV
Best Regards,
