1. The Schottky diode (S.D.), in figure 1 must be type MA735, with Reverse current (I
R
) < 1.0µA at reverse voltage (V
R
)=10.0V
2. “Supply Current 1” is the supply current while the oscillator is continuously oscillating. In actual operation the oscillato
r 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(I
IN
)”
3. Switching frequency is determined by delay time of internal comparator to turn Lx “off”, and minimum “on” time as determined
by MAXDTY spec.
