Note 1: Absolute maximum ratings indicate limits beyond which damage to the device may occur. Electrical specifications do not apply when operating the device
beyond its rated operating conditions.
Note 2: OUT may be shorted to GND for one second without damage. However, shorting OUT to V+ may damage the device and should be avoided. Also, for tem-
peratures above 85˚C, OUT must not be shorted to GND or V+, or the device may be damaged.
Note 3: The maximum allowable power dissipation is calculated by using P
ambient temperature, and

voltage and efficiency.
Note 5: Specified output resistance includes internal switch resistance and capacitor ESR. See the details in the application information.
Note 6: The output switches operate at one half of the oscillator frequency, f
Note 7: The human body model is a 100 pF capacitor discharged through a 1.5 k
