XC9110/XC9111

Series

Note: The XC9110 series, Tr. Built-in type, uses the Lx pin and the XC9111 series, external Tr. Type, uses the EXT pin.

oscillation frequency (FOSC) is 100kHz. The duty ratio of the XC9111 series automatically varies between

56% (oscillation frequency 180kHz) and 75% (oscillation frequency (FOSC) 100kHz).

* The duty ratio depends on power supply.

Please refer to the electrical characteristics on duty against output voltage you use.
