TPS54331: Disable ECO-mode

Part Number: TPS54331
Other Parts Discussed in Thread: TPS54308

The TPS54331 will entry to eco-mode, when the output current is under 160mA. Can I disable the TPS54331 eco-mode by external setting?

Hi,

The function can't be disabled, why do you want to disable it?

I want the lower power ripple, when the system is low loading.

Hi,

Maybe you can try TPS54308 which works in FCCM at light load. The ripple voltage is small than TPS54331, and it is internal compensation.
