Test condition : Unless otherwise specified, VIN=VOUT×0.6, IOUT=<C1(*)>, Vpull=5.0V
NOTE:
*1: TOREX SBD, XB01SB04A2BR is used, reverse current IR < 1μA (when reverse voltage VR = 10V is applied), in case of using selected
parts.
*2: Supply Current 1 is the value when the IC is constantly switching. In actual operation, the oscillator periodically switches, resulting in
lower power consumption. Please refer to Input Current (IIN) under no load condition for the actual current, which is supplied from the
input power supply (VIN).
*3: Lx switch ON resistance can be calculated by (VLx x Rp) / (Vpull - VLx). * Change Vpull so that VLx will become 0.4V.
*4: The Lx limit voltage function becomes stable when VOUT is over 2.0V.
*5: EFFI={[output voltage]×(output current)} / [(input voltage)×(input current)]×100
*6: Please be aware of the absolute maximum ratings of the external components.
(*): Please refer to the charts.
