Functionality at or above these limits is not implied. Exposure to absolute maximum ratings for extended periods may affect device reliabil- ity. Operating ranges define those limits between which the functionality of the device is guaranteed. Notes: 1. The Schottky diode (S.D.), in figure 3 must be type MA735, with Reverse current (IR) < 1.0µA at reverse voltage (VR)=10.0V 2. “Supply Current 1” is the supply current while the oscillator is continuously oscillating. In actual operation the oscillator periodically operates which results in less average power consumption. The current that is actually provided by external VIN source is represented by “No-Load Input Current(IIN)” 3. Switching frequency is determined by delay time of internal comparator to turn Lx “off”, and minimum “on” time as determined by MAXDTY spec.
