PRODUCTION DATA.
Mixed decay begins as fast decay for a time, followed by slow decay for the remainder of tOFF. In this mode, mixed decay only occurs during decreasing current. Slow decay is used for increasing current.
This mode exhibits the same current ripple as slow decay for increasing current, since for increasing current, only slow decay is used. For decreasing current, the ripple is larger than slow decay, but smaller than fast decay. On decreasing current steps, mixed decay will settle to the new ITRIP level faster than slow decay.
