Ta=25℃
NOTE: Unless otherwise stated, connect VDD to VOUT, VIN=VOUT×0.6, IOUT=50mA. See Typical Application Circuits, Circuit 3.
*1: The Schottky diode (SD) must be type MA2Q735, with reverse current (IR)<1.0μA at reverse voltage (VR)=10.0V.(XC6372E)
*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 external VIN source is represented by "No
Load Input Current (IIN)".
*3: When PWM operates at PWM Mode.
*4: When PFM operates at PFM Mode.(XC6372E)
*5: 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 oscillation frequency are properly stabilized when VDD=2.2V or higher.
