TB9045FNG-125
DCDC2
It is buck DCDC convertor with 6V input voltage (DCDC1). It is a synchronous rectifying type incorporating output driver MOS and rectification MOS. 6V output from DCDC1 convertor must be used as input voltage.  Maximum output current is 800mA. (Set current consumption considering allowable dissipation and heat generation.)  Switching frequency is 2 MHz.  It incorporates functions of overcurrent detection and high/low voltage detection.  It incorporates phase compensating capacitor.  The capacitor connected to DC2Css pin can control voltage rising time.
