●XC9111 E and F series

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.

The XC9110 / 9111 series E and F series have the VDD pin. The XC9110 series' duty ratio is 75% and

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 VLx limit function only applies to the XC9110/9111 C versions.

* The duty ratio depends on power supply.

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