Part Number: LV2862

Hi Experts,

This device supports ECO mode. Customer wants to remove voltage ripple at light load.

1. Is it possible to disable ECO mode?

2. If not, what is the condition when device enters into ECO mode?

LV2862 is fix frequency , once the SW start switch, it will not work in ECO mode, ECO enable is when Vin Vout in normal operation and Iout =0A, the frequency will decrease to enter ECO mode with low IQ.
