Externally Applied Reference Voltage (Vref)

No external connections

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.
