Note:
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 V
IN
source is represented by “No-Load Input Current”
3. The switching frequency is determined by the delay time of the internal comparator and MFO1, which sets the min. on-time
