Test condition : Unless otherwise specified, 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: Please be aware of the absolute maximum ratings of the external components.
(*): Please refer to the charts.
