Notes 1* :
Although the IC starts step-up operations from a VDD of 0.8V, the output voltage and oscillation frequency are stabilized at
VDD
≥
1.8V or (Vref applied voltage + 0.7V). Therefore, a VDD of more than 1.8V or (Vref applied voltage + 0.7V) is recommended when VDD is
supplied from VIN or other power sources.
