The current decay rate of the Decay mode operation can be determined by the DCY1 and DCY2 inputs for
constant-current control.
The “NF” refers to the point at which the output current reaches its predefined current level, and the
“RNF” refers to the monitoring timing of the predefined current.
The smaller the MDT value, the smaller the current ripple amplitude. However, the current decay rate
decreases.
Charge mode → NF: Predefined current level → Slow mode →
Current monitoring → (When predefined current level > Output
current) Charge mode
Charge mode → NF: Predefined current level → Slow mode →
Mixed decay timing → Fast mode → Current monitoring → (When
predefined current level > Output current) Charge mode
