LT1336
Electrical Characteristics The l denotes the specifications which apply over the full operating
temperature range, otherwise specifications are at TA = 25°C. Test Circuit, V+ = VBOOST = 12V, VTSOURCE = 0V and Pins 1, 16 open. Gate
Feedback pins connected to Gate Drive pins unless otherwise specified.

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