Lx Switch-On Resistance
Same as IDD1. VLX=0.4V.
Lx Leakage Current
No external components. VOUT=VLX=10V.
Duty Ratio

Lx Limit Voltage
L,SD,CL etc. connected
Measuring conditions: Unless otherwise specified, connect VDD to VOUT, VIN=VOUT
0.6, IOUT=50mA. See Typical Application Circuits, Fig.3.
1. The Schottky diode (SD) must be type MA735, with reverse current (IR)<1.0
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 consumption. The current actually provided by an external VIN source is represented by "No-Load Input
Current (IIN)".
* When the VDD and VOUT pins are independently used, the voltage range at the VDD pin should be 2.2V to 10V.
The IC operates from VDD=0.8V. However, output voltage and oscillator frequency are properly stabilized when VDD=2.2V or higher.
