2. Step-up Characteristics (Ta = 25
°C)
The data of the step-up characteristics ((a) Input voltage (VIN) vs. Output voltage (VOUT) characteristics (Input voltage
stepped up), (b) Input voltage (VIN) vs. Output voltage (VOUT) characteristics (Input voltage stepped down), (c) Output
current (IOUT) vs. Output voltage (VOUT) characteristics, (d) Output current (IOUT) vs. Efficiency (
η) characteristics
under conditions of 1 to 12 in Table 18 is shown below.
