XC9110/XC9111 Series
■EXTERNAL COMPONENTS
Tr.: *Using a MOSFET
XP151A13A0MR (N-ch Power MOSFET, TOREX)
Note : VGS breakdown voltage of this Transistor is 8V
so please be careful with the power supply voltage.
If the power supply voltage is over 6V, Please use the
XP151A12A2MR with a VGS breakdown voltage of 12V.
* Using a NPN Transistor
2SD1628 (SANYO)
RB: 500Ω (Adjust in accordance with load and Tr’s hFE.)
CB: 2200pF (Ceramic)
CB ≦1 / ( 2TT x RB x FOSC x 0.7 )

■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.
3. The Lx limit voltage function becomes stable when VOUT of the XC9110/9111C series is over 2.0V and the VDD of the
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.
