     CXMD3261 is a DC/DC Buck Synchronous with four current limit pins suitable for many multi‐output applications. It is designed to allow for operating a wide supply voltage range from 9V to 40V. It has both high‐side and low‐side drivers allowing synchronous configuration using two external power‐NMOS. This IC can operate in both Constant Current (CC) and Constant Voltage (CV) modes. CXMD3261 operates as a DC‐DC Buck Controller providing a wide range of outputs at Constant Current (CV) from 1.2V to 28V and the output current as high as 10A or above. It has a Constant Current(CC) mode so that output current can be set externally and at a accuracy of +/‐7%.    The current mode control and external compensation makes feedback control have good line and load regulation with flexible external design. There are four independent current limit control pins for four separate loads. Each of the current limit can be set by a resistor(RCS) at 100mV across it. Of course, output peak current limit is working during normal operation
