Note: Even in Fast Decay Mode, the transition is invariably made to Charge mode for a brief moment to
When the CLK signal is input, the Chopping Counter (OSC Counter) is forcibly reset at the timing of the
As a result, the response to input data is fast in comparison to methods that don’t reset the counter.
The delay time is one OSC cycle: 10 s @ 100 kHz Chopping using the Logic Block logic value.
After the OSC Counter is reset by CLK signal input, the transition is invariably made to Charge mode
