Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 4:
IS is the sum of currents through SV +, PV + and Boost pins. may cause permanent damage to the device. Exposure to any Absolute IBOOST is the current through the Boost pin. Dynamic supply current is Maximum Rating condition for extended periods may affect device higher due to the gate charge being delivered at the switching frequency. reliability and lifetime. See Typical Performance Characteristics and Applications Information
Note 2:
For the LT1160, Pins 1, 10 should be connected together. For the sections. The LT1160 = 1/2 LT1162. LT1162, Pins 1, 7, 14, 20 should be connected together.
Note 5:
See Timing Diagram. Gate rise times are measured from 2V to 10V
Note 3:
T and fall times are measured from 10V to 2V. Delay times are measured J is calculated from the ambient temperature TA and power dissipation P from the input transition to when the gate voltage has risen to 2V or D according to the following formulas: LT1160CN/LT1160IN: T decreased to 10V. J = TA + (PD)(70°C/W) LT1160CS/LT1160IS: TJ = TA + (PD)(110°C/W) LT1162CN/LT1162IN: TJ = TA + (PD)(58°C/W) LT1162CS/LT1162IS: TJ = TA + (PD)(80°C/W) 11602fb 3
