ELECTRICAL CHARACTERISTICS

The q denotes specifications which apply over the full operating

temperature range; all other limits and typicals are at TA = 25°C.

Note 1: Absolute Maximum Ratings are those values beyond which the life

of a device may be impaired.

Note 2: Connecting any input terminal to voltages greater than V + or less

than ground may cause destructive latch-up. It is recommended that no

inputs from source operating from external supplies be applied prior to

power-up of the LTC660.

Note 3: The output resistance is a combination of internal switch

resistance and external capacitor ESR. To maximize output voltage and

efficiency, keep external capacitor ESR < 0.2

Ω.

Note 4: fOSC is tested with COSC = 100pF to minimize the effects of test

fixture capacitance loading. The 0pF frequency is correlated to this 100pF

test point, and is intended to simulate the capacitance at Pin 7 when the

device is plugged into a test socket and no external capacitor is used.

Note 5: OUT may be shorted to GND for 1 sec without damage, but

shorting OUT to V + may damage the device and should be avoided. Also,

for temperatures above 85

°C, OUT must not be shorted to GND or V+,

even instantaneously, or device damage may result.
