(Top and bottom layer back copper foil size: 20.2mm
2, 2nd and 3rd layer back copper foil size: 5505mm2)
Derate by 17.7mW/°C when operating above Ta=25°C. The board is provided with thermal via.
(Note 4 74.2mm×74.2mm×1.6mm, FR4, 4-layer glass epoxy board
(Top and bottom layer back copper foil size: 5505mm
2)
Derate by 28.5mW/°C when operating above Ta=25°C. The board is provided with thermal via.
(Note 5-1) The chip should be used within AC peak limits at all conditions. Overshoot should be ≤30V with reference to GND.
Undershoot should be ≤10nsec and ≤30V with reference to VCC. (Please refer to figure 4-1.)
(Note 5-2) The chip should be used within AC peak limits at all conditions. Overshoot should be ≤OUTxx+7V with reference to OUTxx.
Undershoot should be ≤10nsec and ≤OUTxx+7V with reference to OUTxx. (Please refer to figure 4-2.)
Caution: Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit between pins or an open circuit
between pins and the internal circuitry. Therefore, it is important to consider circuit protection measures, such as adding a fuse, in case the IC is operated over
the absolute maximum ratings.
