EXTERNAL COMPONENTS

Tr.: *Using a MOSFET

so please be careful with the power supply voltage.

If the power supply voltage is over 6V, Please use the

NOTES ON USE

1. Please do not exceed the value of stated absolute maximum ratings.

2. The DC/DC converter / controller IC's performance is greatly influenced by not only the ICs' characteristics, but also by

those of the external components. Care must be taken when selecting the external components.

XC9110/9111E series is over 2.0V.

4. Make sure that the PCB GND traces are as thick as possible, as variations in ground potential caused by high ground

currents at the time of switching may result in instability of the IC.

5. Please mount each external component as close to the IC as possible and use thick, short connecting traces to reduce

the circuit impedance.
