MPPT working principle

6.11

Burst mode

When the output voltage reaches the battery charge voltage, the MPP-SET voltage drops

below 450 mV, or the output current reaches the output maximum current limit, the duty

cycle D drops down to 10% and the device evolves from Operating mode to Burst mode.

The converter no longer works at constant frequency, but at frequencies gradually lower (1

entering Sleep-IN mode.

Sleep-IN mode

Once Sleep-IN mode has been entered, no current is provided to the load. The device exits

this mode once the cause which forced it into this state is no longer present.
