11. Current Waveforms in Mixed Decay Mode
• When the NF points come after Mixed Decay Timing points
• When the output current value > predefined current level in Mixed Decay mode
*: Even if the output current rises above the predefined current at the RNF point, the current control mode is briefly
switched to Charge mode for current sensing.
