1. The Schottky diode (SD) must be type MA735, with reverse current (IR) < 1.0
μ
A 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 comsumption. The current actually provided by an external V
IN
source is represented by "No-Load Input
Current (I
IN
)".
3. When PWM operates.
4. When PFM operates.
