TPS7A78: AC line input cap

Koji Ikeda

Part Number: TPS7A78

Hello Support team,

My customer would like to reduce AC line input cap Cs from 0.47uF to 0.22uF. Do you see any risk for lower cap, except lower output current?

Thanks,

Hi Koji,

The lower current is the primary impact you will see here. If the customer is using HB operation they can try FB operation to help increase the current with smaller values of Cs.

Thanks,

Stephen
