LM3743MMX-300/NOPB Overview
With a 10-TFSOP, 10-MSOP (0.118, 3.00mm Width) package, the switching controller is suitable for a wide range of applications. PMIC is packaged in a solid enclosure of Tape & Reel (TR). With this function, you can deal with Transistor Driver dc switching's outputs (s). The supply and operating voltage of the dc control are 3V~5.5V. Qualified to work in an dc switcher with -40°C~125°C TJ. The switching controller is capable of switching at the 300kHz position. dc dc regulator can be generalized using Surface Mount. To provide efficient switching control, Current Limit, Enable, Soft Start, Tracking is included in the dcdc regulator. SWITCHING CONTROLLER analog IC connects the switch converters. Thare switching converters has a terminal (s) at DUAL . A variety of dc switching's functions can be performed on 10 terminations. LM3743 can be used to locate other relevant dc to dc converter ics. In total, switching converter has 10 pins. Specially, switching converter corresponds to type Switching Regulator or Controllers. A 4.6V voltage of DC regulator was detected in the test statistics. In most cases, the output current of the dc dc regulator will be 20A, so note that when you start the project. A duty cycle set at 91 % ensures voltage regulator dc to dc reliability during power-on and power-off. DC switcher's Surface Mount makes it qualified for most application and prototype designs. DC switcher'sDC regulator has a maximum frequency of 345kHz. During dormancy, the dc switching uses 1.8mA. With this controller, the phase is 1.
