Current Modes
• Sine wave in increasing (Slow Decay Mode (Charge + Slow + Fast) normally used)
• Sine wave in decreasing (When using MIXED DECAY Mode with large attenuation ratio (MDT%) at
• Sine wave in decreasing (When using MIXED DECAY Mode with small attenuation ratio (MDT%) at
Note: The above charts are schematics. The actual current transient responses are curves.

Because current attenuates so quickly, the current
immediately follows the set current value.

Because current attenuates slowly, it
takes a long time for the current to follow
the set current value (or the current does
not follow).
