TPS54331: Is it possible not to go into ECO-mode when the load is 1mA

Danilo A.

Part Number: TPS54331

Hi Team,

Our customer would like to confirm if it is possible for TPS54331DDA not to go into ECO-mode when the load is 1mA. According to the customer, he found out that when the device is in eco-mode, the ripple voltage will increase.

Regards,

Danilo

Hi, Danilo

We cannot prevent not to go into ECO-mode.

Workaround is to reduce the feedback divider resistor or add dummy loading.
