Note 1:
Stresses beyond those listed under Absolute Maximum Ratings
Note 3:
Dynamic supply current is higher due to the gate charge may cause permanent damage to the device. Exposure to any Absolute being delivered at the switching frequency. See Typical Performance Maximum Rating condition for extended periods may affect device Characteristics and Applications Information sections. reliability and lifetime.
Note 4:
Pins 1 and 16 connected to each end of the inductor. Booster is
Note 2:
TJ is calculated from the ambient temperature TA and power free running. dissipation PD according to the following formulas:
Note 5:
See Timing Diagram. Gate rise times are measured from 2V to 10V LT1336CN/LT1336IN: TJ = TA + (PD)(70°C/W) and fall times are measured from 10V to 2V. Delay times are measured LT1336CS/LT1336IS: T from the input transition to when the gate voltage has risen to 2V or J = TA + (PD)(110°C/W) decreased to 10V.
