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. Ta = 25℃ XC9110Fxx1MR, XC9111Fxx1MR ■ ELECTRICAL CHARACTERISTICS (Continued) |
