noted. Typical values are at V
Note 1: All devices are 100% tested at T
Note 2: The MAX5955/MAX5956 slow-comparator threshold is adjustable. V
Note 3: The current-limit slow-comparator response time is weighted against the amount of overcurrent; the higher the overcurrent
Note 4: The startup period (t
Note 5: The current available at GATE is a function of V
