+# DC/DC
+## 개요
+ - 정상 상태 배터리 전압 전압 ( rated_Vbat )
+ - 정상 상태 버스 전압 ( rated_VBUS )
+ - Boost -> Buck 전환 전압 ( V_chgstart = rated_VBUS * 1.01 )
+ - Buck -> Boost 전환 전압 ( V_dchgstart = rated_VBUS * 0.98 )
+## LCD 설정
+ - Gain : Vdcp, Vdcn, Vbat, Ibat (All xxx.x%)
+ - Rated : Vbat(xxxV), Ibat(xxx.xA), Vdc(xxxV),BMC_vtg(xxx.x%)
+ - Protection : Vbat_OV(xxx%), Vbat_LV(xxx.x%)
+ - Setting : Fsw(xx.xkHz), Droop_Vtg(x.x%)
+## BOOST
+ - Feed-forward 
+ - Droop ( LCD 에서 설정된 경우 )
+ - 전압 Reference ( V_dchgref = rated_VBUS - droop_vtg )
+ - CV Only
+## Buck
+ - Feed-forward
+ - CV/CC
+ - 전압 Reference ( LCD 설정값 )
+ - 전류 Reference ( LCD 설정값 )
