LM3743MMX-1000/NOPB Overview
It comes in the 10-TFSOP, 10-MSOP (0.118, 3.00mm Width) package, which makes switching controller suitable for most applications. There is a Tape & Reel (TR) solid enclosure around the pmic. It is capable of handling Transistor Driver dc switching's outputs (s). 3V~5.5V is the supply voltage and the operating voltage of the dc control. Qualified to work in an dc switcher with -40°C~125°C TJ. Using this switching controller, it is possible to switch at 300kHz. The Surface Mount makes it ideal for general dc dc regulator. Switching control is made easier with the dcdc regulator's Current Limit, Enable, Soft Start, Tracking. An analog IC with the SWITCHING CONTROLLER signal is connected to the switch converters. Switching converters are designed with the terminal (s) at position DUAL . A variety of dc switching's functions can be performed on 10 terminations. Other relevant dc to dc converter ics will be returned if you search "LM3743". Pins number 10 of switching converter in total. In particular, switching converter belongs to the Switching Regulator or Controllers family. According to the test statistics, DC regulator outputs 4.6V voltage. If you start a project, note down the dc dc regulator's usual output current of 20A. It is set to 76 % duty cycle to ensure voltage regulator dc to dc reliability during power-ups and power-downs. As DC switcher has a Surface Mount, it's suitable for most applications and prototype designs. There is a maximum frequency of 1.15MHz for this dc regulators. In a dormant state, the dc switching uses 1.8mA. Switches with 1 phases are used in this controller.
