<Setting of Output Voltage>
Output voltage can be set by adding external split resistors. Output voltage is determined by the following equation, based on the
values of RFB11(RFB21) and RFB12(RFB22). The sum of RFB11(RFB21) and RFB12(RFB22) should normally be 1 M
or less.

Output 1 (Step-up DC/DC controller)
Tr 1 :
* MOSFET
XP161A1355PR
(TOREX N-Channel Power MOSFET)
Note : VGS Breakdown Voltage of this Tr. is 8V so
please be careful with the power supply voltage. For 6V
power supply voltage, XP161A1265PR which VGS
breakdown voltage is 12V is recommended.
VST1 of XP161A1355PR is 1.2V (max.) and that of
XP161A1265PR is 1.5V (max.)
Output 2 (Step-down DC/DC controller)
Tr 2 :
* MOSFET
XP162A12A6P
(TOREX P-Channel Power MOSFET)
Note : VGS Breakdown Voltage of this Tr. is 12V so
please be careful with the power supply voltage.
