LT1186F

ELECTRICAL CHARACTERISTICS

TA = 25°C, VCC = SHUTDOWN = DIN = CS = 3.3V, BAT = Royer = BULB = 12V, ICCFL = CCFL VSW = Open, DOUT = Three-State, DIO = IOUT

= CLK = GND, CCFL VC = 0.5V, unless otherwise specified.

The q denotes specifications which apply over the specified operating

temperature range.

Note 1: TJ is calculated from the ambient temperature TA and power

dissipation PD according to the following formula:

LT1186FCS: TJ = TA + (PD)(100°C/W)

Note 2: Does not include switch leakage.

Note 3: For duty cycles (DC) between 50% and 80%, minimum

guaranteed switch current is given by ILIM = 1.4(1.393 – DC) for the

LT1186F due to internal slope compensation circuitry.

Note 4: Timings for all input signals are measured at 0.8V for a High-to-

Low transition and 2.0V for a Low-to-High transition.

Note 5: Timings are guaranteed but not tested.
