General Description<\/h3>\n\n\n\n

EC1736 is a DC\/DC Buck Synchronous with four current limit pins suitable for many multi\u2010 output applications.<\/p>\n\n\n\n

It is designed to allow for operating a wide supply voltage range from 9V to 40V.<\/p>\n\n\n\n

It has both high\u2010 side and low\u2010 side drivers allowing synchronous configuration using two external power\u2010 NMOS. <\/p>\n\n\n\n

This IC can operate in both Constant Current (CC) and Constant Voltage (CV) modes. EC1736 operates as a DC\u2010 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.<\/p>\n\n\n\n

It has a Constant Current(CC) mode so that output current can be set externally and at a accuracy of +\/\u2010 7%.<\/p>\n\n\n\n

The current mode control and external compensation makes feedback control have good line and load regulation with flexible external design.<\/p>\n\n\n\n

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.<\/p>\n\n\n\n

Of course, output peak current limit is working during normal operation<\/p>\n\n\n\n
