ELECTRICAL CHARACTERISTICS
Note 3: TJ is calculated from the ambient temperature TA and power
dissipation PD according to the following formula: TJ = TA + (PD)(64°C/W)
Note 4: The LTC3543 is tested in a proprietary test mode that connects
VFB to the output of the error amplier. This test mode is equivalent to
continuous mode operation.
Note 5: Dynamic supply current is higher due to the gate charge being
delivered at the switching frequency.
TYPICAL PERFORMANCE CHARACTERISTICS T
A = 25°C unless otherwise noted. (From Figure 1a)
