      CXSU63262 contains a Boost DC/DC regulator and a load switch.The Boost regulator adopts peak current control mode and integrates a 120mΩ low R_DS(ON) N-channel MOSFET which is capable of conducting2.5Apeak current. The fixed 1MHz switching frequency and internal compensation reduce external component count and save the PCB space. The Boost regulator also features internal soft start that limits the inrush current at start-up, individual enable control and cycle by cycle current limit.The load switch integrates an 80mΩ ultra-low R_DS(ON) power FET to minimize the power loss. The programmable current limit protects the power source from over current and short circuit conditions. Other features including reverse current blocking and individual enable control.CXSU63262 is available in small DFN3x3-12 package.
