Test condition : Unless otherwise specified, connect VDD to VOUT, VIN=VOUT×0.6, IOUT=<C1(*)>
NOTE:
*1: "Supply Current 1" is the value when the IC is constantly switching. In actual operation, the oscillator periodically switches, resulting
in lower power consumption.
*2: EXT H ON resistance can be calculated by (0.4 x Rp) / (VEXT - Vpull). * Change Vpull so that VEXT will become VOUT-0.4V.
*3: EXT L ON resistance can be calculated by (VEXT x Rp) / (Vpull - VEXT). * Change Vpull so that VEXT will become 0.4V.
*4: EFFI={[output voltage]×(output current)} / [(input voltage)×(input current)]×100
*5: When using VDD and VOUT separately, please set the voltage range of VDD from 1.5V to 10V.
The IC operates from VDD=0.8V, but output voltage and oscillation frequency will be stable when VDD=1.5V or more.
*6: Please be aware of the absolute maximum ratings of the external components.
(*): Please refer to the charts.
