PRODUCTION DATA
When the MODE pin is selected to operate in FCCM mode, the converter operates in continuous conduction mode (FCCM) during light-load conditions. During FCCM, the switching frequency (fSW) is maintained at an almost constant level over the entire load range, which is suitable for applications requiring tight control of the switching frequency and output voltage ripple at the cost of lower efficiency under light load. If the MODE pin is selected to operate in Eco-mode, the device enters pulse skip mode after the valley of the inductor ripple current crosses zero. The Eco-mode maintains higher efficiency at light load with a lower switching frequency.
