XC9801/XC9802 Series
■TYPICAL APPLICATION CIRCUITS
① Regulation Output
② Doubler Output
External Components:
CIN=1μF (Ceramic Capacitor: TAIYO YUDEN)
C1=0.47μF (Ceramic Capacitor: TAIYO YUDEN)
C2=4.7μF (Ceramic Capacitor: TAIYO YUDEN)
Note: The XC9801 series are step-up charge pump voltage doublers which provide regulated output voltage.
The application circuit of the doubler output (②) halts the regulated output function and operates as a normal voltage
doubler.
The output voltage is stable when connected as in (①) above, except when VIN < (VOUT / 2) and VIN ≧ VOUT.
