Reference Circuit Examples
Figure 22 shows reference circuit examples.
ΠWhen used all of the step-up circuit, voltage regulating circuit and V/F circuit
(1) When the voltage regulator internal resistor
is used.
(Example where VSS2 = VSS, with 4x step-up)
(2) When the voltage regulator internal resistor
is not used.
(Example where VSS2 = VSS, with 4x step-up)
