Notes

The Schottky diode (S.D.) in figure 3 must be type MA735, with Reverse current (IR) < 1.0µA at reverse voltage (VR)=10.0V.
“Supply Current 1” is the supply current while the oscillator is continuously oscillating. In actual operation, the oscillator periodically operates, resulting in less average power consumption.
The switching frequency is determined by the delay time of the internal comparator and MFO1, which sets the minimum on-time.
